What did you think of them? I'm curious as to which old games are holding up well without the nostalgia factor.
I played a few which I picked up from GOG.com (with many more not yet played):
Fallout 1 and 2 (1997,1998): Absolutely brilliant RPGs. Tons to do in a truly immersive and unique game world, and always multiple ways to solve each problem, many of which you'll never even notice with your character build. Highly replayable and they'll suck you in for hours at a time. The only negative is that combat takes an eternity when you're facing a large number of enemies at once (rare occurrence).
MDK and MDK2 (1997,2000): I couldn't play the original for long because it lacked proper mouse look functionality (maybe there's a mod or patch to fix that, I didn't check). MDK2 however, is still a good game. Three playable characters result in highly varied gameplay, along with a great sense of humour.
Myst: Masterpiece Edition (1999): When I managed to get immersed in the adventure on the island it was fantastic. Far too much obscure "logic" (common in point-and-click adventure games) broke up the immersion frequently, unfortunately.
The Longest Journey (2000): A much better point-and-click adventure game. Strong writing and a memorable protagonist are its strongest points, and whilst it does still have some bizarre logic at times, it's mostly reasonable enough for you to figure out. Well worth checking out, even if you're not a fan of the genre.
Giants: Citizen Kabuto (2000): Great humour and varied gameplay make this one of the best third person action/adventure games from its era in my opinion. Also, it has jetpacks... they make every game better.
Arx Fatalis (2002): A first-person RPG and dungeon crawl, the likes of which you just don't see these days. Incredibly atmospheric world with plenty to do and lots of interesting characters and enemies to encounter. Highly recommended for fans of old-school RPGs.
Additionally, I picked up Rome: Total War (2004) earlier this year. My first foray into the Total War series, and 4X games in general. After a bit of a steep learning curve, it quickly shot up near the top of my favourite games of all time. There are very few games that I've found to be anywhere near as addictive as this, with a great blend of grand strategy and real-time tactics-based battles.
