It should be exactly what I want, considering how sick I am of all these newfangled shooters and their "improvements" that sometimes just take all the fun out of things. Sometimes you just need to circle strafe like a mofo, carry 600 pounds of guns and ammo, bunnyhop, etc., all at implausible speeds without regenerating health. And without reload or run keys, either, because stopping to reload and moving at less than top speed are for wimps and get in the way of shooting things.
I really tried to get back into it when the first HD remake came out, but having played Painkiller a bunch shortly before that, I wasn't feeling it, and that's kind of dampened my interest in anything else Serious Sam since then. I actually stopped playing after a couple levels out of boredom, of all things, which never would've happened ten years ago. I'd much rather have a new Painkiller game that isn't a complete atrocity, but I gave up all hope of that a long time ago. At least I still enjoy playing the original one...
