Well Hogscape, for me the 80s were my role-playing days, with mammoth sessions of T&T lasting all weekend and a once a week visit to a RPG club based above a pub. I ran many scenarios and campaigns for Call of Cthulhu and played all manner of other games.
As the years have gone by, the RPG has kinda slowed to almost a halt. I suppose the arrival of the little Trollkin (now 2 and a half) didn't help, although I look forward to teaching her all about RPG, T&T especially, in years to come.
Any RPG we do these days, when we can actually get a few friends together, and we are not too tired, is usually T&T, but for the actual time we manage to play these days, I can't see any of us bothering to use the new rules. Maybe I'll introduce some as house rules, but we are all familiar with the spell book and how the game works, and for me, 5th Edition is almost near perfect for a role-playing system, so I'm happy to stick with that.
Having said all that, I bought 7th Ed to support the game and also to add to my extensive collection of T&T stuff, and I'll probably buy anything new that comes out for it, even though we will probably never play it!
RPG club above a pub? There can be no sweeter dream! Is that how you got your nick name?
I'm pretty much in the same boat as you. No trollkin yet but at 40 with a wife who does not and will not role-play, games are few and far between.
On the plus side our gaming group does get together every fortnight and two of the players are T&Ters from the very early eighties like myself (although we don't always role-play). In fact we have such fond memories of those halcyon days that we still recall the antics of our characters from T&T, our longest campaign (2 years allmost non-stop with the same characters). Even when playing other games one of the players will stop to ponder... "What would Oberon Mandible have done here..."
Like yourself and Quoghmyre, I also feel that T&T 5.0 is the perfect gaming platform for out style. As it stands 7th ed seems more a collection of some (but clearly not all) of Ken's house rules rather than a coherent system. Never-the-less we are playing 7th ed to get a feel for the new rules, we might then have a think about what sort of things we're going to pick and choose to add to our 5th ed games.
