So I had a solid play through of C&C recently, somewhat enjoyed it though I found the level design extremely frustrating in some cases and that was more to do with the original game than anything else remaster wise. However it turns out there's an extremely well known bug that hasn't been fixed where when you get to Soviet Mission 12 technically two bugs because it involves units suddenly becoming invincible for no reason and the fog of war not going away. Finished the Allied Campaign with zero problems.
This along with Baldur's Gate 2 in particular and their cultural vandalism of trying to introduce a bisexual character ( forgotten what she was supposed to be exactly but it was the wild mage ) in the game for no fucking reason makes me feel that remasters just shouldn't be a thing. Even with the best of intentions they seem to introduce bugs and never fix them and then to make matters worse because they deliberately wipe the original from the stores that means you can't get the game that would run absolutely fine without resorting to piracy.
Full re-work of the game or bust as far as I'm concerned, use the old assets if you have them, but I don't ever want to see them re-using horribly buggy and glitched code and they should put it on an up to date engine too to prevent problems.
Pokemon Fire Red and Leaf Green seemed alright, but that's about the only positive experience I can recall having with a re-make/re-master.
I think it's safe to say that the only thing old games need is to be made compatible with more modern systems. Leave the actual game itself completely unaltered.
The Metroid Prime remaster that came out like a year ago was pretty good. Mostly a straight-up port with enhanced textures and models.
Very little dialogue or voice acting for some Treehouse jackass to fuck up.
the updated controls and detailed textures were great, but they fucked up the lighting. The original had many dark sections that you could illuminate by shooting down the hallway. The remake is brighter and projectiles don't illuminate walls.
IIRC there were also some mirrored surfaces scattered around the original that were not present in the remaster.
Disappointing but not a deal breaker.
I remember enjoying HeartGold and SoulSilver too but admittedly I haven't played those in 9 years or so.
It's weird, I wasn't able to get into Soul Silver as much as I got into Leaf Green, and Leaf Green was a cartridge I found in the middle of a very busy street by sheer dumb luck. I played that way more than the game I paid good money for because running around properly EV training a Nidoking for the first time was a blast but fiddling with the egg walker peripheral just didn't do it for me I guess.
Pokemon HeartGold/SoulSilver were peak remakes, and it's not even close.
