Deus Ex 1 is one of my most replayed games, I only ever got Ultima 9 which was considered the worst Ultima game ever, but mostly due to the story being completely butchered and not canon, so as I hadn't played the previous ones I didn't care. The fun thing with Ultima 9 as a lot of more recent look back reviews said was they basically tried to make Skyrim but with the limitations of DX6, and it was horrendous to play but for some reason I completed it a few times.
Honestly though I hardly care for the immersion and story over the tactical combat, one of my favourite such games I've mentioned a few times being Tales of Maj'Eyal.
I wish there were AAA graphics games with the same depth of combat, BG3 is close and fun enough but I still wish the combat had more to it.
