Solving the lag issue is only relevant when you do multiplayer over the network. At which point you are committed to a non-trivial engineering project that will take a few months of work to get off the ground. Prototyping the game idea should be done before committing to such a project. It would be much easier to get a dozen friends with gamepads to the same room and play around with a prototype game. Just some rectangles and circles running around the screen. About 1000 lines of code at most so changes can be made on the fly. If it's not fun, iterate until it is. The turnaround time for feedback is much faster. When I read the article I found this to be the biggest shortcoming. Starting work on a half year project with an unproven idea, no market research (playing other games with tanks and steal ideas) and a lot of technical hurdles that don't matter to the final product.
