Magicka

The reason for the thumbs down is not because the game is bad. In fact, I had it before Steam and absolutely loved the spellcasting antics, and its brand of absurd humor. QRASR, QFASA, rogue+haste+ice armor, anyone? The problem is that the game is abandoned in an extremely unstable state, constantly crashing. It takes downgrading to an older versions and maybe external third party help to run; you'll get no official support. As such, I cannot recommend buying it. (PS: I never played Magicka 2, but I did briefly play the PvP version before it discontinued - from what I understand the newer games in the series are no longer as experimental and heavily nerfed compared to Magicka 1.)

A really fun and creative games where you need to use different spells, and spell combinations, to defeat enemies and bypass environmental obstacles. I have a ton of great memories of this game from multiplayer with friends years and years ago. You can get up to all kinds of shenaningans, and the game doesn't take itself all that seriously either. It is pretty comedic, and that helps to get the laughs going. However, at this point it is a bit dated, over a decade old, and suffering from technical issues. Also, I didn't realize it, but it went through the Paradox Process, as I like to call it, and ended up with more DLC than game. I hate this business practice. If you have a group of friends who are set on playing this with you, don't mind working through some technical problems, and can get this game when it is on sale, I would recommend it. However, if you are looking to play this single player, I would probably give it a pass, especially if you can't get it for cheap.
