I could easily recommend this game from what I have experienced in 3-4 hours so far. I have had minor problems with graphics: For some reason, the game doesn't allow me to run the game in 1280x720 or 1920x1080 without making the game unplayable in progress. It's not gamebreaking, as I can play with other resolutions, but as these two would be the most ideal resolutions for me, it annoys the crap out of me.
And the almighty Google doesn't have an answer for this, so I guess I'll have to live with it for now.
Bugs. try to update it to 1.1 or the latest. Also, it has performance problems with ATI cards.
1680x1050 is the best res IMO
Not much sense in using anything else than the native resolution for the monitor, unless the situation is dire. It blurs the image a bit. Makes small fonts even harder to read.
