Level Design
Bigger & wider map
Crysis2 maps were very narrow or small. Only 100~200m even biggest area. I hope Crysis3 has 500m area.
Freedom of the route
Crysis2 was almost no freedom of the route. Most of maps are very linear. Even if some maps have several routes, it's like driver choose lane. Not road. Choosing lane, choosing road, they're totaly different. And I hope that we can pass many buildings. It's important. The building which we can't pass limit route, gameplay. I want ladders, too. There are building, but we can't climb!?
More vertical
Crysis2 vertical gameplay was weak. I hope Crysis3 has much more up-down, much more range of height. I want to shoot enemy from hill & roof of building.
Less respawning AI & stop close-range spawning
Frequent respawning is annoying & very unnatural in some cases. Please use more carefully. And please stop close-range spawning. Not only it cause a visual problem, but also it brings limitation of gameplay.
Game Design
Less energy cost of sprint
Big energy cost of sprint made strong limit of movement in Crysis2.
Less energy cost of power attack
We need all energy for power attack? That was rediculous. It makes power attack garbage.
More meaningful pickable object
This is important point for gameplay. There were very few meaningful pickable objects in Crysis2. And, there should be several kind of barrels. Because flammable barrel is bad as pickable weapon.
Meaningful driveable vehicles
Meaningful, this is important point. Not only driveable.
Meaningful suit modules
Most of suit modules were garbage in Crysis2 campaign. Please re-design.
Less QTE
As many many gamers said, QTE is garbage in most cases.
Enemy
Normal AI
Crysis2 AI was very buggy. It was one of the most biggest problem in Crysis2. CELL & Marines throw grenade towards an obstacle and blow up themselves. AI don't notice sound of cannon. AI don't notice crash sound of car. High frequency stuck. I was surprised & became very sad that last boss stuck... I don't need super smart AI, I want normal AI...
More variety of enemies
We can already see several kinds of new enemy units. But an important point is individuality or characteristic in gameplay. It makes fun. They stand, walk, run, shoot or not... Crysis2 aliens were so in most parts. They're just hyper human as gameplay. Boring.
What I want is... for example, some aliens use barrier (I think Crysis Warhead type was good. Group leader make barrier for other members), some aliens fly (and grab & carry friend to anywhere anytime. this is great... we aren't safe at the roof of building), etc.
Others
Better Lean
Lean system of Crysis2 wasn't good. Very limited position & strange camera.
Skippable cutscenes
I can't understand why Crytek made unskippable... it's just waste of time in replay.
Credits after Ending
"No Credits after Ending" was one of the big fault in Crysis2. It's very important point for players.
