The Saturn is very low on my list. That being said, it does excel when it comes to accessories. The arcade ports are mostly excellent, and the arcade sticks will take you far for all the great fighting games (nab a 4Mb RAM expansion too).
The real winner for me is the multitap, which allows for complete gaming madness with 10-player bomberman and 7-player Death Tank Zwei, amongst others. These are game you need to experience as a gamer, and if you haven't I can honestly say that you're missing out.
It may not look like much, but Death Tanks Zwei is all about gameplay, which it has in spades. Sheer chaos awaits as everyone launches volleys of shells at once. The winner nets the lion's share of points to buy better weapons between rounds, quickly snowballing them to complete victory, but it's still great.
Keeping track of all the placed bombs becomes quite the task with 10 players. Online multiplayer has nothing on local.
Well, as long as you're willing to deal with this...
