Open up OpenTTD on the rare occasion I fancy gaming.

Any regularity? I suspect you meant reasonably often, but assuming a more liberal interpretation, I still take a stroll through Myst (93) from time to time and also the Secret of Monkey Island (90) and although I admit that the latter is the remastered 2009 version, it includes the original shitty graphics at the touch of a button. I have Zork Nemesis (96) and Grand Inquisitor (97) loaded although I haven't looked at either for a while. 

I pretty much don't, usually of the opinion that nostalgia is best left untainted by going back. I'm gonna play Day of the Tentacle and Grim Fandango soon though. Hmm, if I ever played on the SNES Mini I reckon they'd be the title-holders for me.

Currently the only game I play regularly.

I'm not as good as I used to be, but then I guess I probably only play as much in a week now as I did per day before, if that.

I regularly load up Street Fighter 2 on the RetroPie build I've got, and I play Pharaoh (city building game in ancient Egypt) a fair bit too, I think that's from 99-ish. That's a brilliant game and has a great sandbox build-your-own scenario/mission editor tool.

 

What RetroPie build are you using?
Maybe this would be better on a new thread. I think there's a few of us interested.

I still sporadically make the mistake of losing a day to Civ2.

Oldest game I have installed (and have played in the last year) is Head over Heels - a Spectrum game from 1987 in PC remake form, and it's still a great game work of art.

Entering a room and going "I remember this", then flashing a puzzle because of a 25-30 year old memory, does give a warm fuzzy feeling.

Now I'm thinking of how dumbed-down such a game would be if made today, and it's made me sad. :'(

I recently re-installed Unreal Tournament and had some royally good fun with it! OpenTTD is also fun for a good retro-blast from time to time. Other old games I still enjoy playing are Raptor (needs DOSBox), Dungeon Keeper II and Warcraft 3.
