EvE: trial for a week then moved to:
WoW: trial and wanting more, but didnt want to be pulled in like I know I would and then
WAR started, you all know that story: 2-3 months and later F2P-ish that just didnt pull it
EvE: blame Jon - 2+ years
LOTRO: few months of subs, then F2P which didnt quite keep me in
Champions online: trial, meh...
blame lean wallet and my last sliver of sense
