I actually had fun with both, but even though I acknowledge that Episode 2 was technically the better game for having better controls, physics and the like, I honestly enjoyed episode I more. I can't even explain it, sorry. Recently there was a topic about how big a part the music plays in making a level memorable. Splash Hill music may be shit, but fucking hell do I remember how it goes and so I remember my time spent in splash hill and my memories are actually good. Fuck knows what the music is like for Silvania Castle or whatever its called. I'm sure it plays better but it's just so forgettable. I know what you're thinking if you hate episode 1, "WHY IS MEMORABLE GOOD IF THE MEMORIES ARE A BIT SHIT"...well quite, like I said, I can't even really explain it. Bottom line is that I'm far more likely to go back and replay levels from I rather than II.
Sky Chase remake was a buzz though.
