I also highly prefer 1.2, nubcake. In addition to all the variable changes, there have been tons of non-variable changes. Actually there aren't many things that haven't changed:
Mark decon, bp queue, build timers, free funds, score,
Humans:
ackit, blaster, painsaw, shotgun, MD, prifle, chaingun, flamer, luci;
repeaters, turrets, armory, dc, tesla;
stamina, sprint, dodge, headshot damage
Aliens:
granger slash, speed, basi gas, grab/slash ranges, heal aura; mara zap, walljumping; dragoon chomp, pounce; tyrant maul, trample;
barricades, booster, hive,
hovelhp and healing, bbox sizes
and much, much, much moreAnd it's 4 years... And LOTS of things have been added server-side in 1.1 since it's release, incl bug fixes and admin features, GUID...
Everyone can add a ton of single 'cool' gameplay features, but in 1.2 all the things work together much better. Many high quality models will be added. A new HUD will be made. At least 1 awesome map is being made. What more do you want?
