Oh shit. I almost forgot Rising Zan Samurai Gun Man... Yes I went there. That game was fun. Also, Tenchu 2. I fucking love that game. I still have all my custom levels. Thrasher Skate and Destroy was another one I really liked.
Strangely enough, Alundra is probably the Only PS1 RPG that i owned and never managed to finish. Something about either my TV, or the graphics engine used for the game gave me something approaching motion sickness if i played it for longer then about an hour at a time. And it is quite literally the ONLY game i have ever played that ever did that.
