Bringing the Thunder
One could probably make an argument that FRLG are the worst remakes though, that was 1:1 also but lacked animated sprites, stopped evolutions, restricted transfers until post game and even then required a cumbersome mini quest.
Ehh, kind of, but most of this was a product of its time. Remakes and third versions didn't quite shake things up as much then as they did in games like HGSS and ORAS, so expecting FRLG to completely overhaul RBY was perhaps too lofty an expectation. FRLG did go above and beyond by giving RBY a lengthy post game experience in the form of the Sevii Islands, which is more content than I could say for the likes of LGPE, BDSP, and arguably ORAS (whether or not FRLG or ORAS has the better post game largely depends on your preferences). Animated sprites also weren't as much a regular thing back then, Crystal was the only game prior to FRLG that had them. As for the stopped evolutions, well LGPE and BDSP are worse than that, as not only can you not evolve them before the post game, you can't evolve them period. Anything that wasn't in the original RBY simply does not exist in LGPE and likewise anything that didn't exist in DP did not exist in BDSP. So that much is an argument against FRLG being the worst.
I'd also argue HGSS is slightly overrated too since it runs off Gen 4's slow af engine
Personally doesn't bother me, but for those that are bothered, again, this is a product of their time. Remakes and third versions always ran on that gen's engine, so if HGSS came out in 3rd or 5th gen, for example, they wouldn't have had this problem.
I also think ORAS was ruined Gen 3 with all the mega BS
Megas were the least of ORAS' problems IMO and I actually think Megas improved ORAS. ORAS' biggest issue is that it totally ignored Emerald content and didn't feel like the definitive version of this game that a remake should be. If a 9 year old third version that's no longer on the market is better than your remake, that undermines the incentive to actually buy the remake.
