1991. Year of Civilization.
1994. Year of X-Com.
1995. Suikoden in Japan ('96 for US, '97 for Europe.).

But I'd have to say 1995 overall; the PS1 came out then (US and Europe at least.), along with many awesome games (Loaded, Battle Arena Toshinden, Warhawk (OMG SEQUEL!), Twisted Metal, Fade To Black, WipeOut, etc. etc.)
