Welcome Roger,
You will get settled in in no time at all,and when your game arrives you can kiss goodbye to your previous life!
And before long you will be asking "what are the latest mods,what are the latest expansions,or add-ons?" ,and we will say "take your pick mate,there is thousands to pick from!" , but first be sure to get GWX3 (Grey Wolves Expansion) as soon as you have had a test drive with the default game,it is the way forward my friend.
Have fun!
