Very risky with these 1 hit wonder mobile companies. Doubt they will ever get their money back, Supercell made $930M profit last year, $950M in 2014. They'd need to remain another 8-9 years at the top spot for Tencent to get their money back, and we know with mobile devs they usually crash and burn once they're out of fashion and the masses move on to the next big thing, which happens every few years.
