Very few titles available at a system's launch are ever worth the price of admission. Thing is, they don't have to be: early adopters don't have any other choices, and they certainly aren't taking home that shiny new box with nothing to play. If a launch window game isn't a glitchy, feature-stripped port of a last-gen game, then it may just be the best of the bunch.
Ubisoft in particular doesn't have a great track record when it comes to launch games. They were the first third party to reveal their Wii hand with the ambitious and roundly disappointing Red Steel, threw straight up shovelware at the DS, and didn't exactly set any precedents at the dawn of the HD era, either. For the 3DS, Ubi's launch day contributions took the forms of Rayman 3D, Asphalt 3D, Combat of Giants: Dinosaurs 3D, and Ghost Recon: Shadow Wars.
It doesn't surprise me, then, that Ghost Recon: Shadow Wars is a technical mess. The visuals wouldn't turn heads on PSP, slowdown is common, and everything just feels rough around the edges. Oh, and then the game freezes every now and then. Sometimes you'll get the black screen of death, other times the audio will stop and the display will just fade out. In the time I was playing, Shadow Wars crashed on me a grand total of ten times.
What surprises me is that, despite these glaring technical issues, I will still recommend the game to 3DS early adopters.
