My current FFXIV obsession has me wanting to play the older mainline Final Fantasy games I never played/finished. Are any of the PC ports so horrible I should avoid them? They generally have positive ratings (aside from the FF VIII remaster for some reason), but I thought I'd double check.
Most all of the FF ports are perfectly playable in my experience, though they can have minor issues. The first two XIII games, for example, were pretty stuttery on my end. Check the forum discussions, typically if there's a problem it takes up 90% of the page.
FFVII is also immensely moddable, and there's a 4K texture pack for FFIX that has AI up-scaled versions of the backgrounds that generally look fantastic.
Also if you're obsessed with FFXIV I'd play FFIII first, thanks to all the references in the Crystal Tower raid series and beyond.
