I just deleted Metro 2033 off my hard drive, ran an erase on the dead space, removed and burned the drive and urinated on the smoking carcass.
I played maybe an hour before being overcome with rage.
Imagine if Stalker had sex with Hellgate London and their deformed, drooling, bastard offspring kept all the bugs and quirks of both.
A brief list of annoyances.
In town, the character voices are all the same level, regardless of direction and distance. In a crowded area, you have 14 loud conversations in your ears.
Outside of town you have to wear a gas mask, because of course the world is poisonous. You really can't tell how much time you have left on the mask filters, or if the next one is any better, so you can't plan for the mask exchange. When it fails, it fogs your vision and you have heavy breathing noises. This always happens in combat. The maps are complicated environments but there are invisible walls everywhere, forcing you to go... somewhere. You don't have a map so you're running blind (from the mask), trying to find your way through the level to an unmarked objective.
You randomly find guns, but you have no way of knowing if its better than what you have.
The buttons for control have dual purposes if you hold them down. "F" for flashlight also brings up your flashlight battery charger. So in the middle of combat, if you mean to turn your light on and hold for an extra second, the charger pops up and you have to fumble for keys trying to get rid of it, then turn the light on or off.
It has save points and you can't quick save.
It has crap loads of cut scenes.
