I walked into a local gamestop looking for a fighting game, having never heard of GG or even Arcsys before, made an impulse buy, and now shudder to think how close I came to never playing CT.
I just barely managed to beat story mode the first month, and never really got into the game until the PSP port was released. I was very handheld oriented at the time, and played it for far too long.
When CT came out, I bought it for the cannon continuation, and loved everything about it. New art was so eyegasmic, new mechanics worked brilliantly, gameplay was smooth as butter.
Just great games.
