Europe - Android Apps for European Travel

I posted a request on a technology forum and didn't have any good suggestions, thought this might be a better place. I did a search here and couldn't find anything either...

I'm looking for particularly good apps out there to use on my tablet and phone for an upcoming international trip? I have Fring credit for VOIP calling, so I have the Fring app, but i'm interested in :

fun addictive games (possibly ones that don't kill the battery)
any GPS things that may be useful
specific travel apps (im sure they exist)
anything particular for Switzerland and/or France
anything particularly good for long trains/planes etc.

Deutsche Bahn Navigator (more than just German schedules)
Öffi Station (bus schedules -- works GREAT)
BierApp (find biergartens in Franconia)
Google Translate
Google Goggles
Weather Underground
Lufthansa
Kayak

Google Maps (this one speaks for itself really)
Railteam app (train schedules for all over Europe)
Doodle Jump (very addicting)
RATP app if you plan on going to Paris
Plants vs Zombies (very fun game)
Temple Run (very addicting game, and free)
