My personal favorites:
Kid Icarus Uprising (suprisingly good, however you may want to try before you buy because the control scheme is very divisive)
Virtues Last Reward (Pick up 999 (first game in series) for the DS and play that before you play this game!)
The people who decry mini sentries in regular pvp are just whiners.
In mvm though, I would question your use of a mini sentry, especially when regular sentries build instantly in set up mode and you have an upgrade that gives you a free additional mini sentry. In my experience...
Forgive me O Mighty Ocean for I have sinned:
I do not like 2d mario games.
I did not find Skyrim, my first Bestheda game, engrossing.
Psychonauts was ok.
I do not like final fantasy 4, the only final fantasy game have finished.
I do not like pokemon.
I did not like SMT:Strange Journey...
