Haha ta! I LOVE Twinsanity. I love the way the levels were integrated. It didn't feel like separate worlds or prtoal like previous games with I loved. It gave the series a lovely diversity and the transitioning between levels made the game feel like one big adventure, not several little adventures which was something I really enjoyed. Not to mention having to solve puzzles and whatnot to unlock art and gems! It was by far one of the best in the whole series.
BUT in saying that, nothing will beat the originals. (1, 2 and 3). I love all the Crash Bandicoot games up to the mutant series really. That's when I think Crash Bandicoot was ruined and has lost it's spark. :(
