I've always been a big fan of turn based strategy games. I like to plan and think about each move, none of the fast thinking required by RTS games (maybe I'm just getting old LOL). Although there are some great TBS games out there, I think there are many more just waiting to be born.

My favourite games of all time are the Heroes of Might & magic series (if I had to pick one, it would probably be III). I'm also a big fan of Civ VI. The TBS games that got me hooked so many years ago were Laser Squad, shortly followed by Battle Isle on my trusty old Amiga (ah, the good old days).
