Zombie Highway's never really been a freemium game. It has gone free a few times, but it's a paid app.
Not always... i liked TT and PF (tiny towers and pocket frogs) Oh and, i really liked great big war game, are you making a 3rd?
Yes! I got into the Solomon dark games after they were free and enjoyed them enough to spend some IAP money. Same story with Major Mayhem. To be clear, neither of these were designed as freemium games. Games made to be freemium are all, in my humble opinion, garbage by design.
