Dont worry Destiny community isn't really competitive and there won't be so much salt or toxic people like other competitive games. From the experience i had with destiny 1 on ps4 it was super welcoming and helpful. You wont need the first game since everyone will have a fresh start. You just need to learn the ups and downs of the game in the first few weeks. But from then on, join in in the bungie forums and you will have an AWESOME time. go for it Guardian
