Comet should come with expansions 1 and 2. This would encourage the players to buy the new content. Or, there could be a different package that includes the first two expansions with Comet for a slightly higher price. There could even be a premium package that also includes passes for expansions 3 and 4. This would reward the player for purchasing the expansions and they would be more likely to buy new content and keep playing. What do you guys think?
