Looking to buy, I have some questions.

I’ve wanted to experience Arma for the longest and after seeing mod support and the community behind reforger I’m looking to make the purchase.

My question is, is it really worth it on Xbox, is there kbm support(I haven’t built my pc yet but want to get used to using those peripherals), if not do the controls feel awkward?

My other question is, in case of purchase, what servers are best to play on. I’m not opposed to the retro servers but i am looking to play some of the more modern ones as well.

Thanks.
