I guess I had my Original Xbox for a while before Tom Clancy's Splinter Cell came out. This, more than any other game - to me - showed off the graphic possibilities of that generation of consoles. Not only that, but I had never really played a "stealth" game before, and the gameplay was entirely new to me. I love how you could use your gadgets or whatever in different ways to solve missions. I also loved the night vision, that was cool.

I was obsessed with this game for a while, and got great enjoyment out of playing it. Strangely, I've never really played any of the sequels, though I've heard some of them are pretty good. I think if they released a new one and it was well reviewed I'd probably buy it. 

The game had some great locations and lighting effects, and I can still remember prowling around in it. That the lead character was voiced by legendary B-Actor Michael Ironside was a huge plus. 

I don't play stealth games too much anymore, but I do own a copy of the last Hitman game I bought during a PSN sale and I recently re-downloaded it to try it out. When it's done right, stealth can be a lot of fun. 

Splinter Cell was a lot of fun.
