Is it true that LCD screens aren’t good for games?

The answer to your question is totally subjective. It is a fact that LCDs in their current state of technology cannot refresh the screen as fast as a regular CRT, but LCD refresh limitations are steadily being overcome. I have seen games that I thought looked good on an LCD and someone else did not, and vice versa. You know what you do and do not like. Go check out a few LCD screens and decide for yourself.
