Not games I have discovered recently, but these are some truly great games I come back to every 5 years or so:

Heroes of Might and Magic 3 - to me a perfect mix of exploration, building and your own power creep. I've tried some of the later iterations but they all just weren't as good

Darklands - early RPG based on 15th century HRE/Germany with a magic system based on christian saints and miracles. Made in 1992 and amazingly an open world game

FF7 - Always amazing to play again

Alpha Centauri - Not played this for a decade or so, so don't know how it's held up. I kept coming back to this game for a long while. Newer versions such as Endless Space and Stellaris are good but just don't seem to have the same wonder that this original civ in space did, but might be because I've seen it all before.

From the next 'era' of games I would say look at Bioshock 1/2/3 and Deadspace (which I think has been redone recently to rave reviews but unfortunately poor-ish sales so that's probably nixed a Deadspace 2 remake which was even better)
