1994 had my favourite game of all time; FFVI. 1992 had me getting my first console; the SNES. 2007 had the Orange Box. I refuse to choose between any of these, though I should probably add 1998, 2001, 2004, and 2008 for the years MGS1-4 were released. It's easily my second favourite series of all time, and all of those games are still sitting right up there with the Half-Life series for game design in my eyes. I'll stop listing years there though since HL and HL2 are covered as well.
