For a first time EP purchase I'd recommend Snowy Escape, it's hardly the best pack in my opinion but I find the pack is kind of like a sampler of content. You get a new career, a new world, festivals, great new CAS and Build Buy, you get a bit of seasonal gameplay, new sports activities, a fair amount of family activities, and lifestyles too. You get a bit of everything, so new players can play with it and learn what they enjoy most. Enjoy the world? Then maybe other world oriented packs are your thing. Enjoy the career? Then maybe Career oriented packs are your thing. Enjoy the snow? Then get the seasons expansion. Etc.
