I tried avengers alliance I think after all those Zynga facebook games I got tired of the whole using stamina/points to battle, wait & recharge strategy games. It also reminded me too much like Men in Black 3 just without the base creation level between battles.
Someone on the android deal thread suggested
Pacman Monsters, since its another puzzle RPG, but with Pac-man. I gave it a shot & all those other RPG card games started coming back to me. If this game was actually made by MObage it wouldnt surprise me, since it plays like almost all their games. I swear it was blood brothers mixed with "puzzle" elements, which arent really even relevent. It will be uninstalled soon.
I forget what MMR is, its either Match making rank or mutual masturbation rectally....I strongly think its the first though
Definitely not the MMR you're thinking about since thats a vaccine which has nothing to do with MPQ.
