They really should have waited to release TR: Underworld. Bad timing -- too many extremely highly anticipated games coming out at that time; i.e. Spore (PC), WoW: Lich King (PC), Left 4 Dead (multi), Fallout 3 (multi), Gears of Wars 2 (X360) and Fable 2 (X360). Q4 is a too-crowded time to drop a new game, if the big boys are dropping -- and boy, did those big boys drop in Q4 or what!
They should've waited for the right time to drop the game -- like NOW. There's really nothing BRAND NEW on the market dropping like...this Tuesday. January would've been the perfect month to drop this game, since not many big titles drop normally January. By January, people are usually playing catch-up on what they missed from Q4 of the previous year since so many games crowd the market at that time -- and some by now have been hit with a price drop and then some. Having something like a big name game like a Tomb Raider drop now in January with a brand new game would be...well, perfect, I think. I think TR has enough name-power to drop a brand new game in a slow market to the point where people would shell out good money -- especially if it's decent enough.
They should've waited to have the game in a little bit of a better condition, too. Early reports of the TR: Underworld game not being that great and having some issues weren't good, either. Dropping the game in a much better state would've helped -- i.e. such as an improved camera system. Dropping in January 2009, they could've had more time to polish that up and whatever other issues the game had.
Regardless, I'll probably pick-up TR: Underworld, in due time. TR: Anniversary was pretty good. Though, I still do need to find TR: Legend.
