So much I have accomplished, as Chrono Cross is one of the most extra-laden games out there. I got all 44 characters (some will tell you there's 43, but they're wrong), I even used all of them! I saw all 10 endings, even the actual "ending" this time (the normal one just ends, literally; the final boss dies and then the credits roll!) Somewhat fortunately though, the "real" ending wasn't all that amazing, so I didn't miss out on that much through those years. Granted, unlike the previous games I "played the crap out of," I had to go on the internet to find out how to get some of the endings and a few of the characters, but I knew I would be 20 years older by that time (to get every character and ending it's more trial-and-error than common sense). I also got probably 95 percent of the items, weapons, and elements, because I'm sure I didn't use every combination of characters in every area, but good enough! In case your wondering, you can't get every character in one playthrough.
This is only 6.8% of the total playable character roster.
Now, I have to wonder, "What's the next game I'll play the crap out of?" Legend of Dragoon? Non-PS1 games like Final Fantasy X or Dragon Quest VIII? Knowing me, I'll probably go for the hardest one, so Dragon Quest VIII here we come!
