Recommend me a game! I'm looking for something casual (to play for 20-30 minutes from time to time), challenging (like in difficult to master), not super complicated (I don't want to spend hours learning all the rules), but not super simple (when it's too repetitive the patters get ingrained in my brain. anyone else has this?), cheap (don't want to spend $30 on a game I will play from time to time). Must work on Linux and on an integrated GPU. Games I enjoyed previously:
What I did a lot years ago was to play single levels of games over and over until I totally crashed it even if I wasn't that interested in the entire game. I guess what I like most is figuring out the smallest details of a game, not getting into long campaigns.
So, what can I play?
Edit: Thanks for all recommendations so far but I see I need to add one more requirement: no levels. I'm looking for something quick, in and out, skirmish, death match, melee type of game. Not something where you build a character, solve puzzles and so on.
I'd recommend Borderlands 2. It runs beautifully even on Intel HD4000 and it's less than $5 on sale. It's much better with friends, but I've enjoyed most of it by myself and absolutely love it.

Fairly easy. I found a guy with a huge sword and good melee weapons. I was able to smash everything and save enough ammo to just shoot my way through the last hoards.
