I have been a fan of the series from the very first game on and have played every Sam Fisher game since. Recently I started playing Splinter Cell: Double Agent and noticed that I am really not having fun playing it anymore. I still enjoy the concept of the modern ninja but the gameplay just hasn't evolved over time and is beginnig to feel stale and boring to me. I also couldn't care less about Sam Fisher. Sure, the thing with his daughter is tragic but the SC games never were strong on the narrative side, so I never began caring about any of the characters or the particular story arc.

From what I saw it has seemed the gameplay has had some big changes. For instance, I saw where you can queue up enemies Rainbow Six style then Sam goes into some pretty cool animations to dispatch them. That seems like it would help with some of the difficulty when facing multiple enemies. Not sure about how all the sneaking will factor yet. Most of what I saw was pretty action oriented.

Beyond being repetitive at this point in the series, DA also just wasn't a lot of fun to play (IMO).  I've played through every Splinter Cell game and couldn't finish Double Agent.

If you've seen Conviction for one second you'll know it's plenty different.  And while Sam isn't the most developed character I think a lot of people, me included, really think he's a cool character.  Seems like the new game will be more personal.

I think that your Splinter Cell fatigue could be more accurately attributed to DA not being a very good game.  Chaos Theory is the absolute best in the series.  I have a feeling that this game is going to be awesome as well.

good bump

It looks like they changed the gameplay sooo much, like how fluid and easy it is to aim which really makes you feel like an elite soldier,

I love Chaos Theory. It's a game I go back to pretty often. All the dialogue clicked between Sam and his team, the layered system for both the AI and alarms was fair, all the gameplay mechanics were super-refined and the level design was ace. As far as stealth games go, it's one of my favorites.  
 
Really looking forward to Conviction despite it looking nothing like CT, though.

i hope you're right
