well, I played the demo for bf42 loads when it came out. God knows, I must have wasted a year on it.
Full version wasn't a disappointment either.
The thing is with the demo is that you can play alongside full version people as long as they are playing the demo map ... so as far as I am aware even 5 years on the demo is still good to play on
And it is the best map too
Maybe we should organise a wwiizone team?
