Well, my first impressions were with how beautiful this game is - even on my poor graphics card. The textures and feel of the game are excellent.
Then, I logged into the Infantry taster mission. And died. I had expected the enemy to be just... "There" and... what killed me? That speck in the distance? WHAT!? I smiled broadly as I realized how realistic this felt. I'm not one for war games - I have avoided CoD etc. etc, and really bought this game more to support the company as I liked what I saw. I really didn't expect to enjoy it as much as I have!
After five attempts I finally finished the Infantry taster and literally jumped for joy.
Lord knows what I'll be like when the full game comes out...
