>>54144860I wouldn't change gen 1 with time travel other than like fixing bugs or some shit, but I would make changes to the broader development of the series as a whole after that, namely the green column of picrel
>GF expands team with 3D devs and switches dev pipeline/game engine to the modern state way earlier, which cuts down dev time and procedural difficulties they increasingly experienced as the series moved into 3D and then HD according to their recent dev conference talks>XY and ORAS get delayed to launch as N3DS-enhanced titles. The former has the Xygarde cell gimmick transplanted from SM as a post-game activity>SM are instead developed as Switch launch titles, being largely the same story wise but with some mechanical enhancements from USUM (e.g. Mantine Surfing) and Let's Go (e.g. overworld Pokémon spawns). One minor note: in Sun, they're called Infra beasts and Infra wormholes instead>Instead of Let's Go, they instead develop Infrared and Ultraviolet, sequels to SM taking place in present-day Kanto with new protags and an expanded map a la B2W2. Several story elements from USUM get transplanted here (e.g. Ultra recon squad, Necrozma, Rainbow Rocket, Fallers, etc) as well as some new features like Kantonian forms of newer-gen mons>SwSh launch acording to >>54149623 with the DLC included as free updates post-release>PLA is basically the same, just better polished in terms of graphics/performance I guess>OP (a.k.a. SV) launch on the Switch's successor hardware with no bugs, a perfectly stable frame rate and nice looking graphics
