Here's my thought for the day, somewhat related to my previous post on addiction. I'll make this short and sweet.
1. The best game for me is one that can get me addicted to it. If it's just meh, that means it's boring and I won't play it. Hence, in my universe, a really good game is addictive. It makes me wanna play it.
2. If a new game can't hold me for more than 15 minutes, chances are it's boring. So I won't play it. Those first few minutes are crucial and they can make or break my impression of the game.
3. Finally, a good game in my book should also have high replayability. I won't mention WoW here (oops I just did) but Diablo (especially D2) is a good example.
I am forever searching for games that fulfill these basic requirements. Unfortunately these days they are few and far between. I haven't played another game apart from WoW for years, simply because there hasn't been one good enough to keep me interested. I tried Fallout 3 (having played the previous two excellent episodes) and I couldn't do it for more than an hour. I'm not giving up hope though. Once in a blue moon I come across a rare gem such as Borderlands and let's not forget that Diablo 3 is on the horizon. Viva el addiction!
