I have an Ngage, and trust me: You don't want one.
So far, I have only found 2 decent games for it: SSX Out Of Bounds (snowboarding)
and Pathway to Glory.
MotoGP for this thing is a joke. The framerate is 8-10FPS at best. It is unplayable.
I got mine for 100$ after rebates, so I'm not that disapointed, I guess. It has virtually no copy protection on the disks, and piracy is rampant. If you want it, it's out there. Trouble is, there isn't much out there worth a crap.
Hopefully Civilization for Ngage will actually get released and I'll buy it.
Trust me though, If this thing didn't play videos/mp3's and have bluetooth, I would have trashed it long ago...
