ONLINE GAMEPLAY INTERACTIONS.
As for what I would personally like to see in the future games would be a large scale or small scale online interaction for player to player. Be this either making specific servers persons can purchase or a large roaming world for people to interact on I believe people would be far more satisfied to have their sims fall in love and live with someone other than a personally created character for them. This in my opinion would make the game far better and there are probably a million ways to do so. I understand it will be hard and not the easiest thing to develop but the most recognized games never had just the easy to make stuff on them. This would make the game far more appealing and interesting as you guys have the best virtual gameplay so far and this would take it one step further. Than you for your time.
