I have two O^2's and I love them both.
I think in many cases the gfx are better than the Atari 2600's.
The flicker in many 2600 games sucks. Most of the O^2's games are very smooth and flicker free.
The sounds are definitely in need of help though.
I think the games are by far some of the best ideas ever.
Take the Money and Run
Attack of the Time Lord
KC Munchkin: the best Pac Man clone ever!
Invaders From Hyper Space: totally Kills...awesome game, especially with a bud
There are tons of really good games for this system. I actually started a few myself...never got around
to finishing them up though.
