Linear isn't always bad. In the last week or so I've replayed both Portal games (for about the fifth time each), and they're about as linear as it gets. Love those two games. I know everyone's keen for Half Life 3 but I'd personally much prefer Valve made Portal 3.
I'll probably play through the three Bioshock games again soon, too. I started the first one on the pc a few months ago but I much prefer to use controller than kb/mouse (I know kb/mouse has a lot of advantages, but it's just what I'm used to) and my controller wouldn't work on the old pc for some reason.
Mostly been playing FTL (on pc) this last month or so. Have got over 80 hours racked up on it, and have completed it lots of times, but there's so much more to do. Have completed it with less than half of the ships available, and I hope to complete it with each and every one of them - and the different ships require different approaches and strategies. Very good game (though rather hard - I still occasionally resort to "savescumming" - backing up my save file from time to time, when the game's supposed to be a rogue-like).
