As do most people. I've been in the gaming community long enough to see past the complaining most people do. It was most prevalent in my MMO days. People would hit up the forums, tell the world how much they hate the game and then devote 12 hours a day to it. How much could one really hate something when they do it longer than anything else one does in a day?
I stopped listening to the vocal minority a long time ago.
Wasting money on a game is different from person to person. You may hate a certain game and I may love it. I won't stop buying from a publisher or developer just because they make some bad games. Each of the studios above have made games that I love. Maybe not BIS, but the rest yes. Do they make more games that I dislike? Absolutely. But they do also make games that I get a lot of enjoyment out of.
Again, subjective. From a realism standpoint there probably won't be any competition. But if I feel like playing a game like UT, will GB give me that fix? No.
And that, sir, is how we are different. I see life from a different viewpoint. I choose to accept what I cannot change and either enjoy it or not support it. I've received more enjoyment out of games since I adopted that philosophy.
