And rubber-band AI.
Would be better to get the Master System versions of these games when applicable, though.
Unfortunately there was no Master System version of Triple Trouble, which sucks because after being dissapointed by Chaos after finally getting to play it in SA:DX - it would turn out the game is a LOT more fun and on par with 8-bit Sonic 1 and 2 when played on the improved Master System resolution.
If somewhere deep within the bowls of SEGA exists a never released Master System version of Triple Trouble, I would adore it if they could release it so the Master System can stop being an awkward trilogy where the third game is drastically different from the previous two, and start being a quadrilogy split into two "chapters" of gameplay style.
