Siegor: Having turned 34 last month I'm glad to see a lot of people over 30 here. One thing I've noticed over the last few years is that I'm not really into long games anymore (took me almost 2 months to finish Pillars of Eternity). 8-12 hours is ideal for me (apart for the ocasional RPG with a good story which may take 20+hours). 
 eksasol: I have this problem. With work and all the responsibility now it's hard to get into these RPG that have 2 hours long introduction. I just started playing Grandia yesterday while waiting through the storm, and it took until 50minutes before I see the first monster. 
 Similar thing here, but for me the big time constraints seem to have bumped the strategy games off my playlist. Whether its really true or not, I just always have this feeling that there is this huge "barrier to entry" for strategy games vs RPG/action/adventure, where I feel like I need to sit down with the manual and really learn the game systems as I'm starting out. Where the RPG/adventure games I always feel more like I can jump right in and learn as I go.  
 I swear years ago I used to play about 50% strategy games and 50% RPG/action/adventure. Now the strategy games get somewhere between 0-10% of my gaming time and my backlog is littered with all these "cool sounding" strategy games that I haven't touched. And I kinda miss them! Damned responsibilities... :P  
 Oh and 43 here, and glad to hear we have GOGers in their 60s and older. That will be me in 20 years :)
