I'm not going to turn down a system that I know next-to-nothing about (save a vague description in some magazine).
But as it stands it seems like there's an emphasis on FPS play, just with some crude recharging aimed shot ability added in. TB involves more then just aimed shots - tactical opportunities, AP management and choices of various levels of severity
(aside from the lacking implementation of TB in Fallout 1/2. Yeah, I said it, I think the way Fallout implemented TB did little to promote tactical play in any way. Glorified slot machine most of the time)
