I haven't played a video game in ages, so I don't even know what switch I'd want for that application domain. I use a keyboard for typing, and so that's why Topre and MX silent red are my switches of choice right now.
However, if I were playing video games a lot and Topre switches weren't getting the job done, I'd just put together a gaming keyboard with some other switch and leave the Topre board for typing. I see no value in tying oneself down to just one keyboard if you have to compromise one of your keyboard contexts just to make the other one ideal.
