  • Do you know a strategy game like "stonkers"?Hello to all. Do you know a strategy game like "stonkers" with a CONTEMPORARY movement of troops? Thanks!

    I have no idea wot you mean by 'contemporary movement of troops' but two war strategy games I really like are 'Arnhem' and 'Desert Rats'. And if you like them perhaps you would also like 'Theater Europe' and 'Tigers in the snow'.
