When I say update, I mean bringing myself up to date by having the full game.
beachandrats you don't have to purchase the new content to be up to date with the game. Updates are free and often contain free content too. In fact some examples this year would be the new free skin details from a few weeks ago and free content with the regular Events that are taking place. We've had quite a lot of free content this year so far and another Event is on the way in Autumn. I do have the full game but many players do not. You can play the game you have and still have a great experience or you can choose to add more DLC, whether it's a kit or a full expansion pack. If you do see a pack you're interested in you can make a considered purchase by checking out other players opinions in our General Discussion section where you'll find both positive and negative thoughts to help you decide. But you don't have to add anything in fact I know a few people who just play the free base game without any add ons at all and still enjoy doing that.
I'm adding a link to General Discussion, if you want to scroll through you'll see pack opinions and you'll also see players thinking about adding new packs and asking for recommendations. It's definitely not required to make further purchases though. I would like to add I do hope that you're feeling better now.
