The controls were my main issue. Like Dead Space but worse.
The controls aren't as bad as Dead Space 1 when playing on KB/M if you ask me. Dead Space 1 never got a proper mouse control scheme. It's why even when mouse sensitivity is set to max it feels clumsy just turning a corner, or especially turning around. There IS a workaround for it though. You just go to the device input file and set the max mouse sensitivity higher. You need a range anywhere from 2 to 5 times the default depending on your mouse DPI and your sensitivity preferences, but it makes it WAY easier to turn. The problem of aiming remains though, where center screen aim is sluggish and side aim shots are fast, due to the aim being schemed for gamepad toggles with dead zones. Fortunately they sorted out mouse control with Dead Space 2, but I'm still kinda pissed they never patched it in with DS1.
The main complaint on controls regarding TEW when I was chatting on the Steam forum for the game was matches not always burning corpses. I found it to be a non issue because it was simply a matter of being close enough for the match icon to appear, and of course getting there before they got up.
I guess we could go round and round on game design, but what I loved about TEW 1 was the AI are very smart and unpredictable, more so than any horror game I've played. They will keep running at you to the last point they heard you running, and you never know if they're going to swat at you when lying prone. I've seen some on the Steam forum insist stealth is broken in TEW 1, but honestly, those are people that haven't a clue how to deal with the sophistication of the AI.
Regarding TEW 2, sadly control wise things have gotten worse. They added a stick to cover system, and unfortunately it's buggy. It can take a while just to get stuck to cover and lined up properly for a cover takedown, but getting unstuck from it when you want to sneak out from it is even buggier. I believe it's because they made it so you can stay in cover around corners by pressing W when the arrow to do so appears. You CAN however move away from cover to get unstuck from it, but it's often slower than when using the stick to cover button works to detach from it, so it can screw up your timing.
TEW 2 is way too easy even without using the cover takedown skill, but with it, it's laughable, especially since the AI is so dumb anyway. I also don't like the open world design, because it seems just like an excuse to have you returning to the same areas over and over. The game has nowhere NEAR as much variety in level or creature design as TEW 1, and anyone who was put off by TEW 1 will realize that if they ever play TEW2.
Regarding the AI WAY dumber in TEW 2, they don't run very far to chase you, and all you have to do is run out of sight of them to lose them. It's like sound isn't a big part of their scripting anymore. The crafting system is more simplified too. Instead of disarming traps you just pick up weapon parts.
I hate to say it, but they did to TEW 2 the same thing Crystal Dynamics did to Tomb Raider when they went from Anniversary to Underground. The focus is now on graphics and one size fits all simplicity. Just like the relics and artifacts now lie out in the open in clay pots you kick or boxes you raid, the upgrade parts are just found, and not dynamic in use.
