Yeah, I've seen their apps do well everywhere. Even iOS. It's worth a look to see if you like any of the games they have on offer.
I think Virtual City, Supermarket Mania, Airport City and Mahjong Artifacts are the ones I've seen that have good reviews across most app stores.
And I'll second what Green Planet said - If App Developers see good sales and good reviews then they'll be more likely to port over more apps. A company like G5 that's porting over most of their apps deserves praise.
