This game is amazing, even after a decade of existance. While not very appealing visually, the gameplay is fun and solid. The tanks operate off of an armor basis. As in all but the lightest vehicles cannot be harmed by small arms. Tanks with lighter armor will suffer much more damage from tank shells than a tank with heavy armor.
The amount of units surprised me, as there are almost a dozen different infantry squads, as well as almost two dozen tanks and armored vehicles for each side (excluding the French Resistance). You can also realistically build up your base of operations with MG nests, AT bunkers and more.
I sometimes question if the enemy AI are actually trying to kill me or just exploring and happen to find my base, but then again, it's very advanced for 2004.
Finally, you have the ability to call in aerial reconnaissance, a light bombing strike, or even carpet bombing. There's even stuctures and vehicles that can counter these strikes.
Overall, I still find that this game can fit well in modern games aside from the graphics.
Definately buy this if you have the spare cash.
