I have mysteria

I bought this game when it first came out for usa then Tsr sewed them for the whole name thing they recalled but I got to keep my now very rare game

my friend is offering 150 bucks for it since he collects sega things.. was wondering if I should hold on to it or not?
Yeah, I didn't think it was rare. I have it (PAL) and I payed $10 Australian for it (5 of your US earth-dollars).
I actually beat it twice (with about 3 years in between).. I liked it, the story was mediocre, but the battle system was quite similar to shining force etc.

it takes a bit to get into it, but it's worth beating it once.
