I finished Persona 4 Golden today. Took me nearly 80 hours, which the fastest I've ever beat that game by at least 10 hours. But I guess I just know it inside out now.
I managed to max nearly every S.Link. About the only ones I neglected were Adachi's (never done it), Margaret's (couldn't be bothered spending the cash to summon), Eri's and Ai Ebihara's. I got the Fox up to rank 9, but I never bothered with the fishing minigame in this run so I couldn't take it past that.
I also maxed all social stats really early on. I feel like avoiding reading books until I got the speed reading really sped up how I built those stats up. That made the S.Links easier as I had very few roadblocks to rank up certain S Links like Nanako's and Dojima's, while letting me get access to some of the job-related ones before the summer.
Overall, though, it's still an amazing game that holds up in 2020. I've replayed some games from back in the day that feel really old-hat, and despite its low-end graphics and some bits that feel old compared to its sequel, P4G managed to hook me and keep me engaged for the whole ride. Obviously I've recommended it many-a-time, but having played the PC port from start to finish, I really feel this is a great port of an exceptional game and heartily recommend it.
