Best Ending: I'm going to have to go with Leisure Suit Larry 3 on this one. I can't think of too many games with endings where your characters actually end up in a completely different game. It was just funny as hell. Too bad they didn't have voice in that game.
Worst Ending: Phantasmagoria 1. All that time and bullshit wasted just for THAT? Absolutely pathetic. UGGGHHH....just thinking about about it makes me want to find Roberta Williams and strangle her.
