I just got an email from GamersGate saying that Dragon Age Origins for Mac just dropped in price to 5$. "Weekend Sale". Thought I'd check the price for Dragon Age 2 for Mac, and found it to be 12$. Also very reasonable.
I played through Dragon Age 1 and 2 on my PS3 and while I loved the lore and plot of both, I found them to have a lot of performance hitches, and in DA1 I could really see how the combat would be better on a PC/Mac. So I think I'll purchase these two titles.
Just thought I'd give a heads up to other Mac users.
Edit: here is the link. 13$ for both.
