Yes it's possible for you not to use credits but the people that will have to help you will have used credits. The really amusing thing is learning how much people have spent on this shitty game . I was a hardcore player in the early days. I totalled up how much I'd spent on it last week. I got to £1100 ( Americans can convert to dollars yourself ) now my top VIP ranking was 16 I wasted I'd guess £200 not levelling right by opening dorms first. By the time I'd stopped spending I'd slipped too VIP 49. My guess you won't get a straight answer from the other players about how much they've spent ( they will be pretty embarrassed to admit it ) but yeah VIP now I'd guess £2000 for rank 50. Top 10 players well god knows how much but I know personally I have better things to spend on.
I've never used credits and I just LC'd.you have to be good at tut market and have good friends you can work with on attaining LCBC together.by yourself is hard but not impossible.I will lcbc without credits I'm positive I can do it
