Aaaaah, Wesnoth. One of the only game at my disposal during my time on Linux. Fun and rather difficult game.
And from what I saw of Bulletstorm, it's so sad. It had plenty of great ideas, but many poor design choices too. Comfortable design choices, mixed with less comfortable, but cool elements. As the saying goes, it has its ass between two chairs. Oh well.
Anyway, on my side, I'm playing Chaos Rings. A Squeenix RPG for the iPhone. Great interface, really pretty, and some good music going on. It's a costly thing, but it's worth it.
