I haven’t, but I have seen videos of the gameplay. Whew. That’s bad. It has the same “my gun looks where I’m about to go!” which makes no sense in an FPS. I can’t even remember if Red Steel had straffing, or if the straffing was just broken due to the magical sideways weapons.
The sad thing is that you could do such an awesome FPS on the Wii with its controllers.
Half Life 1 was mostly quite linear, except for “On A Rail” which could be approached in a few ways. There were a couple other areas where you had some options (Blast Pit, Interloper), but overall it was not (compared to, say, Thief) a game in which the level design gave the player loads of discretion.
I guess if you want to declare HL2’s physics meaningless, you can go ahead, but I had a hoot with them. That’s meaning enough to me.
