OK, I'll bite, seeing as you asked nicely :beam:
44 - but I'm still getting over the shock from when I turned 25 :laugh4:
Yup, I remember the days when computer games were white dots bouncing around making "blip" noises. My, how they've grown ...
Certainly MTW has had me hooked for a few years now, and although I tried RTW that sort of went back in the box after about 2 months. What I really like about this style of game is its open-endedness, it's not just a matter of going from level to level in a repeatable predictable way, or how fast you can click a mouse. Replayability is where it's at, really, with so many factions, eras, and all the mods!
The one advantage of being "older" is that I've spent a smaller proportion of my life on it compared to someone who's still a teenager but playing as often as I do.... :laugh4:
