yeah, it's a good one to start with. it has some strange stuff like the movement speed system, but you get used to it. If it turns out too strange for you, you can try Conviction or Blacklist. they feel way more modern.

That's cool, Chaos Theory is super cheap so I wanted to try, I like stealth games but never played any Splinter Cell, Blacklist is also on sale but seeing from reviews that the game has some technical issues.
