Grumpy Gamer waxes from experience (he’s one of the guy’s who did Monkey Island) on how economicaly feasable a classic style 2d adventure game would be today. To sum it up, if it did happen, and you tried to do it right, you are going to have a tough time of it. But that doesn’t mean it’s impossible, just don’t be expecting them to be replacing Doom 14 or Half Life 4 anytime soon.
