Usually I'm a big fan of keyboards being used in games. Mouse + keyboard is a better control scheme than just about every gamepad ever devised.
Usually.
However, things start to go bad if the keyboard won't accept certain commands. For instance, if I already have two keys pressed down, it won't register a third key. This causes HUGE problems for games like R-Type, where I HAVE to be firing and moving and controlling the Force device all at the same time to succeed, where a split second's hesitation/lag on a comand can result in death.
So: is there anything I can do to fix this? Is it something that wireless keyboards are prone to? Should I invest in a gamepad? Or is this just a problem with the computer game itself?
