Game Or Store Updates? What's Going On?

@Blondboy2835There's nothing suspicious going on, it was all actually very above-board. The final expansion pack, ITF, was released in late 2013, the final meaningful game patches in Jan 2014 and the final store set in Sept 2014 -- the last few months of store sets were clearly created prior and were just waiting in their queue for release back then. The game concluded its development cycle and there was no TS3 development team after that January. They all left or were put to work on other games (including TS4, of course).

This has always been how the end of development cycle has gone when an iteration of the game has concluded its evolution.  That doesn't make TS3 any less fun to play, but no there isn't going to be a WA 2.0 or other new worlds forthcoming from EA beyond what the existing 11 expansions and the store already have.

There's tons of player made content out there; perhaps you might look for custom content tombs and custom designed worlds that include tombs if designing your own isn't really what you had in mind?
