comment Are references to other games considered an infringement of copyright?
"Ask a lawyer" has become a standard phrase for all legal issues and appears in many instances where this advice will not be adopted. People aren't stubborn, but answering incidental and trivial law questions is neither a lawyer's actual job, nor worth his salary unless the stakes are high. Yes, you can be sued for getting it wrong, but you might not be, you can be anyway and it's not necessarily worse than bad work advice getting you fired, bad cooking advice making you sick, bad relationship advice getting you divorced... We shouldn't tell people to consult a lawyer when they should not.

comment How to implement accurate frame-rate-independent physics?
@1337: The interaction potential is not relevant here. Calculate the acceleration a(t+Δt) as you would normally. If the acceleration depends on the current position, use x(t+Δt) for that instead of x(t). E.g., if the object collides between t and t+Δt, you first update the position with the velocity before collision, but you then update the velocity with the acceleration after collision.

comment How to implement accurate frame-rate-independent physics?
@1337: Euler assumes that for the duration of the past Δt, the object has been moving at the new velocity. Verlet assumes that during the last Δt, the velocity has gradually changed to the new value and takes the average velocity to be the midpoint between the new and the previous velocity. Example implementation.

comment How do I prevent memory-modification cheats?
If I had to implement this form of cheat prevention, I would be sincerely disappointed if hackers caught on to my evil scheme and just gave up. That would mean I've wasted nobody's time but my own.

comment How do I maintain game balance while promoting interaction between dead and alive players?
Depending on how much a player has invested in the game, he may or may not be interested in the outcome of the match. If he's not, what are you hoping to achieve by encouraging them to stick around rather than start a new game?

comment Balancing Attack to Defense in a text based RPG
Not an anwser, but quick coding advice: you're using a lot of bogus variables here. The top four lines could also be written: $power = $baseAttack * rand(3.6, 4.4).

comment Why don't all games permit changing the field of view?
Surely the advantage is not unfair if the competition has a FOV slider as well.
