Hi Daaap
I too was a little perplexed by all the abbreviations when I first came here, so I will try to give you a list:
ICS=Infinite City Sleaze, rapid expansionism. DaveV wrote the definitive explanation, but I do not know where to find it. (help)
OCC=One City Challenge, which is self explanatory. Paul wrote the definitive guide, and I do have a copy on hard drive. If you would like a copy either post your e-mail or leave me a message on my A/C here.
WLT*D=We Love The **** Day celebrations, with these populations can increase rapidly. (It took me ages to figure this one out.
(C)MGE=(Civilization) Multiplayer Gold Edition. It even took me a while to figure this one out, now this was really dumb because this would be the disc in my machine
The next most heavily abbreviated things are the Wonders, HG (hanging Gardens), GL (Great Library) etc. It sometimes leaves me stumped to work otu which one is being talked about. I then have to open up civ. Which is dangerous as I often end up wasting a few hours on a game when I have other things to do. I always tell myself, 'just ten minutes to see how much I can get for this caravan' this inevitably leads to 'just....until I finish the wonder' then 'just ten more minutes until I wipe out the ***' etc etc. (sorry for ranting and raving o)
Right now I can't think of any more to tell you, but there must be others too. I know how frustrating it is seeing all these abbreviations in posts and not knowing what they are.
