especially Mega Man X. I have yet to play much of the original series. Only Mega Man 3. The X series is so fast and the controls are so precise and perfect.
favorites being Mega Man X1, X2, and X4.
I've only beaten the first 4 and played a little of X5 (the interruptions from that annoying little girl that I can't remember the name of were really bad and unnecessary)
Others that comes to mind
- SSX (1, Tricky, and 3. so stylish and fun) - Crash Bandicoot (2, 3, and Crash Team Racing are so damn good) - Mario (for 1, 3, Wario Land 1, and Yoshi's Island. but Yoshi's Island is barely, well you know) - Counter-Strike (1.6 is by far my most played game ever. The Deathrun mod is so brilliant. I love the fact that no sound is needed and it's a nice blend of every genre I like.) - Ratchet and Clank (1 to 3 are so fun. Deadlocked was good too. real different but the coop was fun while it lasted) - Tony Hawk's Pro Skater - Tekken (3, Tag, and 5)
I have yet to get real into Castlevania. I only played the original and it was really good. Been trying to get into Bloodlines but it's not really happening. I have a feeling after I play 3 and Symphony of the Night it'll be up there.
edit: forgot Super Smash Bros, don't know how. Played Melee so damn much. Then got the original and liked it even more. The game feels so free and dramatic. Hell I'd probably pick Smash Bros. over Mega Man I like it that much. Again, the controls are so perfect. The game has a lot of charm. Every match is like a movie. Even though I played Melee a lot more, now I like the original more. It has a magic Melee doesn't.
