SNES - Pretty good but not particularly impressive. Of particular note are the backgrounds for the hall of stairs, and portrait gallery, but most of the game tends to use a lot of repeating patterns and textures.

Mega Drive - There's slightly less detail in some sections of this version. The biggest change here is to the outside areas which used to have parallax trees and a moon, now replaced here with a repeating pattern (the other differences are usually more minor, such as Uncle Fester's portrait being missing). For the most part though this version's detail is basically the same as in the SNES version. I think that the big disparity in the overall graphics which can be seen in these screen shots is probably based more around colour use (more on that in the colour section).

Atari ST - The base detail is pretty similar to the Mega Drive version, though the graphics have been noticeably compacted to make way for a status bar at the left hand side.

Amiga - The detail in this version is very bad. The foreground detail is comparable to the other versions but there's absolutely no background detail at all for most of the game, just blackness.

SNES - Not bad. Everything looks pretty nicely coloured and blended, but the game definitely doesn't use the SNES hardware to its fullest in this area as some of the areas tend to look a little bland.

Mega Drive - This is probably the area where the Mega Drive version takes the biggest hit. The colours used in this version are much more ill fitting here, and don't blend as well as they did in the SNES version, giving a grainy appearance to many of the environments. One of the sections which has noticeably inferior colour use is the portrait gallery (see screen shot). Generally most of the time in this version there's less colours used on screen, though there are a few exceptions here and there, such as the kitchen screen shot above which contains a few more colours than before.

Atari ST - Adequate. Probably the worst colour use out of the ports but at least it has backgrounds, which puts it ahead of the Amiga version by default.

Amiga - Just like the detail section, due to the lack of backgrounds the Amiga version falls down in the colour area too.

SNES - The animation is fairly good, it moves pretty smoothly and has a nice selection of different animations.

Mega Drive - Pretty much exactly the same as the SNES version.

Atari ST - Not too bad, though certainly not as smooth as in the console versions.

Amiga - Much worse than the other three, the enemies especially move in a far less smooth manner, this is mainly due to the game's much lower frame rate.

SNES - It scrolls very well, and has many sections containing background parallax. The parallax here in certain levels is actually very nice and really helps to bring those sections to life.

Mega Drive - The main scrolling is also very good, however this version is missing a lot of the SNES version's parallax and as such looks much flatter.

Atari ST - Bad scrolling, this version uses push screen scrolling instead of the constant scrolling found in the other versions, it looks a little ugly and has a slightly detrimental effect on the game play, but not anything too serious. This version is also missing the SNES' parallax (as a whole the computer ports seem to have more in common with the Mega Drive port)

Amiga - Slightly poorer scrolling but it does the job. There's no parallax (Not possible as there's no backgrounds)

SNES - The music here is actually very good, its catchy, and with pretty high quality sound too.

Mega Drive - The music quality is actually awesome and really uses the sound chip quite well, but unfortunately there are a few tracks missing from this version (the conservatory and boss tunes)

Atari ST - Not all the tracks made the cut in this version either, though more seem to have done than in the Mega Drive port. Due to the much lower overall quality to the sound I'd still have to say that this is much weaker than the Mega Drive version though, whether it has more tracks or not.

Amiga - This version's music is much more comparable to the console versions, though in this case I think its slightly worse in quality than the Mega Drive version (which is rarely the case). The conservatory tune seems to be the only missing track from this version.

SNES - They're adequate. One thing I do think is notable is that the sound effects seem to change based on the environment, it may just be my imagination but I'm sure have more of an echo when you're underground.

Mega Drive - Pretty good, but there's fewer sound effects here than in the SNES version.

Atari ST - Adequate, they just about do the minimum required of them.

Amiga - Adequate, but better than the Atari ST version's.

SNES - The Addams Family is a hop n' bop platformer with a big emphasis on exploration. Instead of having a rigid level based structure the game contains one huge mansion all of which is open to the player straight from the beginning of the game, allowing the player complete freedom of movement. There's also some adventure aspects as heart containers similar to the ones found in the Zelda games can be acquired if found giving a permanent boost to health. The layout and freedom of the design helps to create a very deep and rewarding gameplay experience.

Mega Drive - This version plays pretty much identically to the SNES version apart from a very minor layout change in the chimney section.

Atari ST - The most important thing here is that this version is missing the golf ball and sword power-ups (probably due to the rarity of developers making use of two button controllers). The lower quality scrolling also effects the game play a little, and there seems to be fewer enemies than usual.

Amiga - Unfortunately this version is also missing the golf ball and sword power-ups. The low frame rate has a mildly detrimental effect on the game play as it makes it slightly harder to control Gomez, and makes it more difficult to judge the enemy movements.

SNES - Not a lot to be honest, there's a beginning intro with Thing but that's about it. This version is also censored (the bird boss at the top of the tree usually tries to poo on you)

Mega Drive - The SNES intro is here, along with a new secondary intro of the mansion. There's also no censorship here

Atari ST - Much like the SNES version but with no censorship

Amiga - Same as the Atari ST

All versions of the game are actually very good, and all manage to retain the Addams Family's excellent gameplay, but due to the downgrade in graphics and missing power-ups the two computer ports are out of the running for first place. I would say that the Amiga port is probably the worst version, as the missing background graphics do hurt the experience, but whilst minimalistic even that version still manages to be an excellent game.

In the end the winner just has to be the SNES version, the Mega Drive port is very good (even managing to win out in a few areas, as well as being uncensored) but overall doesn't manage to equalise the SNES port in either graphics or sound.
