I think if I could only have 1 EM (my desert island pin) I would have to go with Williams 4 Roses.
Why, pray... you may ask??
You know, typically... on any title, I feel after I play the game for awhile, get a feel for the game, I can become better and better as I play it more. But 4 Roses is a game that just seems to defy this, no matter 'how' much I play it. I mean, sure... I have gotten better at it but not as good as I feel I 'should' be, after playing as many games as I have done. And I can win games on specials and points here and there but it's very, very hard to have a 'breakout game'. That is, a game where you can really rack up the replays on any single 5 ball game. But 'because' it is so hard to do this, I find myself playing it all the time, trying to do this very thing.
