This is a great game. I started with Dom2 at around 12 or 13 (only 14 now) and while it takes alot of time to master (i still havnt
) its so addictive you wont notice. Play a couple of single player games with different nations and pretenders to learn how you like to play and feel free to ask questions here as much as you like.
If you find a strategy you like feel free to focus on improving it but dont forget to play with other nations/strategies too, it keeps the game going and, more importantly, fun.
