Growing Together update contains milestones for many past expansions and game packs. This gives players incentives to explore other worlds instead of just being isolated in San Sequoia. Accomplishing this will make a Sim more of a world traveler who chronicles many different life adventures.
These cross-pack milestones are mainly a side activity. While individual Sims may suddenly autonomously gain a desire to complete another pack’s milestone, there is no Simoleon reward or aspiration point bonus. One should also not feel obligated to purchase additional expansion or game packs for beyond what they already own. EA Play subscribers are also given and for free.
