I have Republic Commando on Switch, and although I haven't played it on any other platforms, it definitely has issues, specifically the frame rate. It's gonna chug a bit basically any time you do anything, but the game is still playable, for me at least. I haven't finished it yet, though.
Another thing that bothers me is the sound. It's not dynamic at all, sfx is either 100% left, 100% right, or 100% both. It's really annoying with headphones. Maybe I missed an audio option, but I'm pretty sure I didn't.
Also, the dialogue is sometimes poorly formatted for some reason, like sometimes a new sentence should've started, but it instead attaches two words likethis. No impact on gameplay, but it makes the game unplayable, if you know what I mean.
