Only you can decide which platform you go for, like what has already been said if you already have an Xbox360 then the Xbone may be the way to go. Personally I'm running with ps4 the second it's available. Destiny looks at the moment that they favour the ps4 but that could simply be marketing. In regards to joining a clan that is again something only you can decide. All I'd say is make sure before joining one that you see who's recruiting and look at their members posts, look at how they're conducting themselves and how they treat others. If you find yourself agreeing with their posts and feel like you will benefit from playing with them then go for it. You can always leave them if they turn out to be not what you expected! I'm currently in a clan that's rapidly expanding (170+) but at the moment we are recruiting on playStation only so that all the members can play together. I'm happy to help regarding whatever you need - you don't have to be in my clan for me to have your back in a fight. You'll find several clans have some really great people in them. The choice is yours!
