True, but many of the mechanics are similar. The most significant difference third person shooters have is that your own position (and particularly posture) is more important than in a first-person one. It is quite possible to make a shooter with a third-person perspective which plays identically to an FPS; heck, there's a non-insignificant number of FPSes that actually have third person modes; that doesn't make them different games.Unit 13 isn't a first person shooter.
In other words, third person shooters are first person shooters with extra mechanics bolted onto them. I can't think of any mechanics that exist in FPS that can't be implemented in TPS; the reverse is not true. This may well be an argument from a position of ignorance on my part, mind.
There isn't anything semantic about the concept of dual analog first person shooters. Semantic would be arguing between dual analog sticks and dual analog slidepads, not dual analog sticks and inherently different interfaces.
Then you're going to have to explain to me how dual analog affects any of the factors people are complaining about in this thread - 'cause I'm not seeing it. I think I might be missing the thrust of your argument, though.
