Morrowind is a great game, sure. I'm a huge Elder Scrolls fan. I've never played Shadow of the Colossus, so I couldn't say. There are also plenty of other games I find amazing. But Mass Effect just blew me away. I mean, I hesitate to call it more than just a game, but it does sort of feel like something massive, like the Star Wars of my generation, or something. And if I had to pick my favorite game ever, or the one game I could play for the rest of my life or whatever, then Mass Effect 2 would ( at this point - we'll see how ME3 turns out ) definitely be it.
