ragnarok online ofcource =) it was my first mmorpg ever, and it was a new world opening up for me. i remember i couldnt put it together in my little head back then all those walking characters were actually controlled by REAL people untill like 1 hour later =p i just came from the ps1/ps2 (not sure) so i never even heard of these type of games.
it was a wicked time, and i get a warm fuzzy feeling everytime i see a screenshot of RO. strangely when i actually play it now i dont got that same feeling for some reason lol, only screenshots do the trick xD but thats just because its getting old now. just like D2, its pretty much the same story, but i still play that game now and then
