I was first exposed to the series by Bomberman 64. I also own some of the older titles as well but the N64 offerings are still my favorites as I really loved the single player mode of those and that's what got me hooked! Though multi-player in most of the games is pretty fun as well, especially Saturn Bomberman's.
I used to buy tons of games from Funco Lands before they too turned to Game Stops. Now I do most of my game shopping on Amazon and specialty stores. ha ha.
