Man I already played through SA1 and I hated it (though it wasn't with the DX DLC, but I'm pretty sure it's the same experience either way). The only two characters that were worth playing were Tails and Sonic. Any other character felt tedious as hell. Knuckle's treasure hunting stages were pretty stupid, Amy was extremely slow, had the most annoying personality ever, and had the stupidest twists to her levels ever (I hated that stupid robot chasing her in every level considering that you can't destroy it with as many hammer hits as you can, yet Sonic could've easily destroyed in one or two homing attacks), Omega's levels were mediocre at best (but hey he had a great storyline right?), and Big's levels were the most annoying in the game ever. It's extremely hard to destroy an enemy with a stupid fishing rod, I would catch everything BUT Froggy, Big sounds like a cat I'd put out of its misery if I ran over it or something, and he had the smallest amount of levels in the game. The ONLY thing that was of worth mentioning in his levels is seeing where Cream's origins came from, but then not even because she's playable in Heroes so w/e
But damn man, SA2 improves on SA1 in every possible way. The controls are less jacked up, the story is better explained than just a bunch of sporadic cutscenes with each character that leave you trying to piece it all together, the levels are less glitchy and better made, the music is better made, and it introduced a ****ing awesome character to the series (who was better left off dead than brought back imo). Sadly PSN and XBL don't want me to play this game because apparently they make every classic game purchasable EXCEPT SA2
