I've been rewatching a few playthroughs of Sonic 3D Blast, and I had played it extensively on the PC as a kid (and a couple of times prior to that on the Megadrive when game rentals were still a thing) and found myself really honestly enjoying the isometric gameplay. I find that isometric platforming is a style of gameplay that never really got fleshed out as much as it could, because it's whole schtick was imitating a 3D playfield, which then got supplanted by full 3D worlds. It was caught in that weird transition period. I'm curious to see if I can make a potentially fun Isometric Platformer and have been looking at examples from the past. One series of games that I feel tackled this interestingly was the Tony Hawk's Pro Skater series on the Game Boy Advance, and I'm curious to see if I can recreate parts of it's engine. It was isometric, but it also had functional half pipe physics, and I've been thinking to myself that it would function well as a Sonic Engine, perhaps in a sequel to Sonic 3D Blast, essentially upgrading the "hard angle" ramps of yesteryear. Does anyone have any experience with such engines and have any idea how the half-pipe movement was accomplished in an isometric perspective?
