That's the closest match I got too (FontFinder directed me to it after its little questionnaire), but
there are subtle differences. The curved letters aren't quite straight on the sides, and the S is very different. Plus, it's a money-cost font, and there's no sense buying a font just for this, especially if it's the wrong one.
Spammish probably has the right idea: use a completely different font, since it's not part of the logo anyway. Then technically it can't be "wrong," just an alternate typeface they use on some of their material.
(Well I guess it can be "wrong" in the sense that Arial wasn't invented yet, but I'm pretty sure I saw some Arial in the game's signage too, so one can't be too fussy.)
