Yup, we had many a discussion in the TOE forums when DA 2.0 came out (i think that was the next update after 1.8g), anyway, when 1.8g was superseded and the planet count was culled we discussed is it fine to never update and use the version of the game with the most planets.
I guess we were looking at it from a "is this in the spirit of the MV" point of view. IIRC we pretty much concluded that as long as everyone knows they dont have to update and that the MV would keep on accepting older versions, you could play 1.0 if you so felt.
So many of us archived and never updated.
Another similiar discussion we had was about the MCC. remember when it had a 100% econ bonus, or still might in DA. We again said should we keep playing with it, or play with the nerfed version. i dont recall the details as such, maybe its just in TA that the nerf came in, but anyway, both topics were greatly discussed.
And now as i type this SS, i think it might have been 1point8C. I'd have to check my archives, i do recall 1point8C being buggy though, but i don't recall why. Pathfinder maybe??
I'm going to reinstall GC2 and play a game or two, but i'll "play" not work at it so maybe a giga abundant all and colonize the hell out of it!
