Usually I'd side with you tony, and while pecon is right, many computer can run minimum with no problems, some people play Blockland on an old laptop that can't handle of any sorts of shaders, and you can't stick a gt 610 or anything like that into a 2002-2005 laptop.
If the game has been working for people that payed for it why should it all of a sudden stop working because the requirements went up for some game modes?
I mean sure you have a point, and while I can Max the game out and have crisp shadows I still think people who can't afford newer hardware should be able to keep playing the game they payed for instead of one day updating it only to find out they can't run it.
I have Three older computers in my house that people still use, one being an old anthlon xp with a ancient nvidia card that runs blockland at 60fps with no issues as long as shaders are not enabled, an older pentium 4 computyer with a HD 6670 that can handle shaders but framerate drops to 30 and below and its unbearable, and an old celeron computer than can only play Blockland if shaders are off, or else I get a stuff ton of artifacts.
But overall, yeah your right on some points, it does ruin some game modes, but Its not worth forcing an update that will leave people with a unplayable game.
I know if I didn't have the best computer around and my game updated and it no longer work I would of been pissed off... and if the game didn't work because of requirements I would of even asked for a refund since I would of payed for something that was fully developed and not in dev.
Not counting the one I actually play Blockland on since I run that one with Max shaders at all time with no issue.
