COC stands for Corruption of Champions, their remake/sequel to the original that was made in flash if I recall right. both games rather good, same as TiTs which you did know the name for. LT and LD are also good games, ironically enough I've personally played all of them mentioned, each one has its perks, each one leaves me wishing there were more games in this niche of a genre since each one leaves me wishing for more from different aspects. just my own opinion on it though.
