C&C is a typical RTS. No hexagonal tiles in any of the C&C-related games. One C&C game was even more like a first-person shooter. But none was a turn based hex-tiled game.
The right image looks more realistic. Where exactly is the problem? Do you prefer smooth glossy doll-like models? I’m sure this “filter” will be optional.
But keep your expectations low: it is a large and quality made mod, but it is made by crazies. So using magic is punishable, no health replenishable… The story is new and well made though.
No idea where is that screenshot from. Maybe some mobile C&C fan project?
