What exactly is 'Generations'?

I would prefer life stages too be updated via patch than a pack, it would add more meat too the bare bones of a base game, I personally dont think a full blown pack is necessary, update babies a bit, toddlers and kids are perfect in the sims 4 with the parenthood pack, nothing that a hobbies pack wouldn't solve too add more stuff too do for them, teens updated a bit, young adults perfect nothing that a wedding and romance pack wouldn't solve, update adults too have midlife crisis, add an optional walking stick for elders, a pram (stroller), graveyard should be base game lots aswell, I would say it what would be very good game packs that I listed, a hobbies pack would give all life stages something too do bands etc, and weddings and romance would add more venues too go on dates and add more too weddings aswell, being able too gift heart shaped chocolates for an example and slow dancing, those 2 packs would also add alot of venues, something that the sims 4 also needs, cinema, a proper wedding venue, golf course, band gigs, a tattoo and salon studio, more kids play park items, play pen and dress up, toy cooker for our young chefs, ballet studio etc the list could go on
