I got done beating the game on PC, and on the whole, I like this game. I don't know if I love it, but I definitely don't regret buying it.
I feel that some of the complaints are overblown. The only real bullet sponge enemies are the big robots and the bosses, and they've always been bullet sponges to an extent. Everything else(even the aforementioned robot enemies) is very manageable with the right weapon, especially if you give it the right upgrades. It doesn't even have to be pure damage. I ran a +fire rate shotgun with only one damage upgrade(flashlight for dark areas), and it served me well the entire game.
I remember two shotting one of the Brother bosses with the Laserkraftwerk, and I was playing on Normal difficulty. Just give it the chargeable beam upgrade, then the rest +damage, and just melt high armor enemies with charge shots.
I got the game for like $20-25, and I feel that it's worth that price. If this was $60, I'd probably be a little sore after the experience. For the price, I think this is a fine Wolfenstein game.
