In my opinion, both games will only make players addict temporarily.
I have been playing both games for more than 2 years, but they just never change much.
The reason is that both games are "round based game", the game is the
same each time a new round is started.
What you need to do is same each time in the beginning, in Warzone we
bridge, and in Tntwars we build cannon as fast as possible.
I don't enjoy both games, but if you want me to choose one,
I would choose Warzone as there are way more differences in each round.
