Obvoiusly nobody remember Death Mask and Nemac IV, two masterpices of UTTER suckfest, so bad that even just leaving the disks on the table in would the drop in airpressure would pose a threat to windows and pressurized canisters.
Horrible game engines, Death Mask wasn't even proper 3D, just 2D sprites rendered in first person perspective and yet it didn't run smooth.
Nemac IV, sluggish as hell, unbelivable poor ripoff of the powerloader from Aliens, the armor looked more like a rollcage with guns.
