Aside from a weaker theme, the initial price point for TE3K makes new players decide on the original version to play over TE3K. Surprising as it seems to some, playing more than one HUD really isn't the norm.
TE3K also doesn't have as much player interaction as the original Tiny Empires. Is nothing similar to a Festival event and the Black Diamond Mystery Vessel does not give "Generosity" as a item, which if you don't know, in Classic TE, forces players to meet each other in person.
So the ideas in point form:
- match initial price point of both Tiny Empires.
- strengthen the theme(s) of TE3K, making level titles more romantic or powerful sounding.
- add more play or occasional events that makes players interact more one and one.
