Here's how I judge how good a game is: ||awesomesauce||=(quality)*(length/price). I rate the original Portal extremely high, because its quality was almost perfect (cool puzzles, humor, but it lied to me about a cake /terribleoldjoke), and I got it for free on a Steam special, so that's great. 'course, even if I hadn't gotten it for free, it would still have been acceptable. IIRC, Portal was never more than $20 on Steam, so that's still ok. Now Portal2 is $50 to preorder, which is way too much for a game that will only be about 5 hours long, no matter how great the quality is. Besides, games like Portal aren't exactly known for replayability, so that's another strike against it. I'll still buy it, of course, just not until its price has gotten below $25.
