You're comparing a 2013-released X-box 360/PS3 console game that's had 17+ years in development and Gearbox hyped up like there was no tomorrow, claiming "It's the
real sequel to Aliens harharhar", to a 90's arcade game. See the problem with that?
It's not a matter of opinion - the game was literally only thrown together as cheaply as possible to sucker Aliens fans into forking over $60.

It'd be kinda like buying a $250 Hot Toy figure and receiving a $15 NECA figure and defending Hot Toys' decision to rip you off because you were still satisfied with the NECA figure.
