After going back and playing Splinter Cell: Chaos Theory, for what is probably the 10th time in the 8 years since it's release, it's really depressed me that this game is the prime example of what's the best out there for the genre. What's even more depressing is how this critically acclaimed game (Specifically Choas Theory) was, instead of being improved upon, changed drastically into an action-stealth adventure.
I'll admit Conviction was fun. Though you can't say that it was anything like Chaos Theory. The true stealth, the timing (Where missions could take you anywhere from 30 minutes to an hour depending on your playstyle), and the sense of vulnerability are really missing from almost all games that have attempted stealth.
Chaos Theory wasn't perfect by any means, but the fact that it's style of stealth gameplay has not been improved upon (Or even attempted) for 8 years almost seems unforgivable at this point. It felt convincing and not nearly as super-human as most stealth games portray these days.
