Best General and Game Apps for Nexus 10?

I have my Nexus 10 now for about six months and absolutely love it; blows away my wife's iPad on so many levels.

That being said...

I am always on the lookout for any cool apps to kill some time, be it games or anything else worth the time.

Any suggestions would be appreciated


Thanks,
