I'll roll with my top ten, because it's a nice round number that isn't too big or too small. Trying to do my Top 5 would probably reduce me to an incoherent mess for several hours as I tried to decide what to make my fourth and fifth.
1. Xenoblade Chronicles
2. Tales of Berseria
3. Ys VIII: Lacrimosa of Dana
4. Final Fantasy XII
5. Disgaea 4: A Promise Revisited
6. Hyrule Warriors: Definitive Edition
7. Pokemon Mystery Dungeon: Blue Rescue Team
8. The Legend of Zelda: Link's Awakening (the original)
9. Dragon Quest Builders 2
10. Monster Hunter Generations Ultimate
If I had answered this a couple of years ago...honestly, I don't think there would have been any changes. Maybe I would have placed them in a different order, but...well, whilst I play a lot of video games and I enjoy most of what I play, it takes a hell of a lot for a game to enter into my top ten and stay there. A lot of them are reinforced by negative experiences with the franchises they're part of, too. Tales of Arise was an atrocious game and reminded me of just how good Berseria was...I have a very hard time deciding whether I prefer Berseria to Xenoblade sometimes. Honestly, my top three have been unchanged since I first played Ys VIII in 2018. The most recent game in there is Dragon Quest Builders 2, from 2019. I am being very specific with Xenoblade by not adding "Definitive Edition" because whilst I appreciate the visual upgrade and small QoL improvements in that iteration, I did not like Future Connected at all.
It's partly nostalgia for the older games on that list, yes, but these are also games I replay regularly, and I enjoy them every time I do replay them. I often think about replaying them when I can't decide what I want to do. I am always making time and plans to squeeze in a replay of at least one of those titles in any given year. Except for Dragon Quest Builders 2 at time of writing (and I'm just waiting for a sale before I buy it on Steam) I have bought them all at least twice on different platforms in some form (I've actually triple-dipped on Xenoblade, FFXII, Hyrule Warriors, and Link's Awakening, and I've bought Disgaea 4 FOUR times now, on PS3, Vita, Switch, and Steam) and I've done everything there is to do in all of them. Disgaea 4's Vita Platinum is actually one of my proudest gaming achievements, because I loved every second of it and I can't wait to do it again on Steam in the near future.
Also, there's a...recency bias, I guess? I've been having cravings to replay some of those games recently. Tales of Symphonia, Pokemon HeartGold, NieR, and Final Fantasy VIII are all conspicuosly absent from that list (they wouldn't be if it was a top fifteen!) but with the former two I didn't have very positive experiences the last time I played them, and I just haven't played FFVIII since at least ten years ago. It's been so long I don't even remember. NieR...I honestly didn't enjoy the PS4 version as much as I did the PS3 version. I liked old NieR more. If/when I play FFVIII again it might creep back into that list if I think about it again. If they ever make a Monster Hunter title better than Generations Ultimate that'll go in there in its stead...although if they keep making games like World and Rise I can't see that ever happening. If there's a Dragon Quest Builders 3 I can see that going in there, too.
My list has been pretty static for a long time, though. When you've played so many games, it takes a lot for something to really leap out at you as special.
