This post is just moronic and ignorant.
Just off the top of my head, games published by Embracer (and their subsidiaries) in recent years:
Jagged Alliance 3
Desperados 3
Aquanox 3
Destroy All Humans 1 and 2 (your Mars Attacks game)
Wreckfest
Guild 3
Spellforce 3
In development are games like Outcast 2, Tempest Rising, Alone in the Dark, Gothic remake, Titan Quest 2..
This notion that they are "doing nothing with IP they bought" it false and idiotic.
