TheMonkofDestiny: I doubt it. The general belief seems to be that they're too heavily embedded into Steamworks' infrastructure for Croteam to bother devoting time into taking it out just to have it released here.
Unfortunate, but that's life I guess.
Apples90: But the disc copy of Serious Sam 2 has no Steamworks integration, right? I'm all for pretending Serious Sam 3 never happened, but I don't see why SS2 can't get a port.
I am all for Serious Sam 2 & 3 coming to Good Old Games.
One of the first high end games I played when I first joined Steam was Serious Sam 3 and they had an insane sale around that time and I built up a library of classics real quick. SS2 is a rough gem.
Complete Serious Sam on GOG and ported to other OS for Steam and GOG is a seriously awesome idea.
Next, should be Serious World. Serious Sam meets Delirious Mental feat. Travis Scott Burger, Miami Salt Life bumper sticker, confrontational road rage woman experiencing narcotics withdrawal holding a sword, as an opening cinematic to Serious Sam World called the cut scene. Serious Sam gets heli-vacuated to an emergency room after getting their arms lacerated by a methmomma trying to stop her running after people in the road.
The hero's burden becomes more apparent when he sees the healthcare costs. Sam has no money, he is paid by the act of saving the world which "pays for itself" and yet the only healthcare Serious Sam is covered by is Extra Life Pickups and Mental Dental.
