Beat Super Metroid today.
Awesome game, really. As I said before, this game still holds up very well even after 20 years. I can see why this is generally considered one of the best SNES games and thereby one of the best video games of all time. I highly recommend it to everyone. It's great.
I've also beaten Botanicula a couple of days ago. It's quite fun and has some very nice artwork, but I'm kinda glad I bought it during a Steam sale because to be honest I don't think it's worth the regular price (9 bucks).
Anyway, I'm going to start with GTA III probably.
