comment How do PC/Mac games detect piracy?
Just as a tiny add-on, there's a great article about the Spyro copy protection that discusses a lot of this stuff as applied to one game, along with some rationale and an interesting story: gamasutra.com/view/feature/3030/keeping_the_pirates_at_bay.php

Yep, that's exactly what I'm doing at the moment. =)

comment Robust “soft” platform collision using SAT
Fair enough, I can see the benefits; I've worked with both Box2D and Bullet and they both appear to have something along these lines. I'm still not 100% sure my definition of "above" is suitable for sloped lines, which probably would have been a smaller and more focused question to ask...

comment What are the benefits of capping frames per second? (If any)
(By the way, I'd highly recommend not capping by way of "sleep"; figure out what your vsync situation is on your platform and use vsync to drive you. It's much more predictable and usually uses less resources.)

comment Robust “soft” platform collision using SAT
Yeah, had no intention of changing the SAT part; there are just a lot of subtleties to the resolution/projection. There are also interesting things to deal with with sloped vectors, but I think I can get away with "center of AABB started on correct side of line". The stateful filter idea is useful, thank you -- but I may not use it, I think I'd prefer to come up with a stateless solution that doesn't involve carrying around a list or an extra bit of information per object-segment pair, even if it's more work. Anyway, +1...

Also fairly well known but possibly a bit difficult for the uninitiated: docs.oracle.com/cd/E19957-01/806-3568/ncg_goldberg.html -- "What Every Computer Scientist Should Know About Floating-Point Arithmetic"
