I've had my nomad in my hands for about 5 hours now, and have been having a blast going through my limited collection. My question is what games do you actively play on yours?

I ask because I've found a few games don't do too well with the screen: For instance: Indiana Jones - Intruments of Chaos looks great, however the character on Flashback appears too small and Sonic plays too fast for me to keep up with what's going on. I'm assuming Mortal Kombat style fighters look great, as do puzzles like rampart or columns.

So what do you play on yours? And what games (or game genre) should I absolutely steer clear of?
