Yeah that super AI that can hit you while sitting in 6 foot grass was awesome. I loved the respawning checkpoints too :P
I had no problems with the respawning checkpoints. If you play while experiencing the feeling of being in a hurry, you will see them as a pain in the ass. I enjoyed the action so much that I didn't care one bit.
As for the grass stuff.. I approached every battle head-on, covering behind objects etc as you pull a bullet out of your arm to them shoot a syringe up your guts right before the enemies flanked you was simply adrenaline pumping.
Really, you can try your best.. but I loved that game to the core of it.
Oh well atleast you and I agree on Risen ^^
