This was one of the toughest year for me to decide
Some amazing RPG's released on PlayStation this year, Suikoden 2 and Xenogears are my 2nd and 3rd favorite RPGs release on PS after FF7. Parasite Eve would be in my top 10 on PS. Legend of Legaia another fun JRPG released this year but I would not put it as high on my list of other 3.
Baldur's Gate and Fallout 2 are both amazing western RPGs that I spent many hours in.
In the end through I had to vote for Half Life as it one of the most important FPS in history and I had so much fun playing it back in the day.
