Why is this a big deal?
Been in development for 6-plus years (that they've admitted to
)
Obsidian's nearly-complete Aliens RPG was killed in favor of this game.
Gearbox used SEGA's money from this game to fund Borderlands 1+2, while outsourcing Aliens to a shitty fourth-rate developer (Timegate).
Gearbox is making a HUGE deal about how they are the "canonical sequel" to Aliens and brought back a lot of the movie talent, setting expectations sky-high.
SEGA has claimed it's a pillar of their Western development strategy.
A deceitful demo consisting of a vertical content slice not found in game and using a different game engine was shown at tradeshows.
The last part is probably why people are so angry - it's not just that the game sucks, it's that the game sucks AND it's been completely misrepresented for years pre-release.
