-Terraria-
So damn addicting, but addicting for all the *right* reasons.
I love building forts, castles, mechanisms, holdouts underground with increasingly elaborate traps and ornamentation. The time I spend exploring translates later into time I spend building, and I have fun doing BOTH, rather than hating doing one and then turning around to enjoy the brief benefits of the other.
Plus, it's LAN-able. This puts its miles ahead of most other "multiplayer" titles I've played this last year.
-SPAZ (Space Pirates And Zombies)-
I liked this a lot more than I thought I would.
The humor is pretty tongue-in-cheek, and the combat is simple but surprisingly fun.
It's sort of like a 2D X3: Terran Conflict, but lighter and with a personality....and a point.
-Orcs Must Die-
Good sense of humor, rockin soundtrack, great gameplay. Placing traps is easier than I thought it would be, and the player doesn't just get to sit there tending to his towers the whole game, unlike a traditional Tower Defense title.
Dungeon Defenders (similar in a sense that it's also "Hero+Tower Defense") has multiplayer, but Orcs Must Die just does everything else better, and it doesn't force the player to grind. Ever.
If only they could make an Orcs Must Die 2 (somehow) with co-op multiplayer...
