@SPARKY1922 I hope you really enjoy your new purchase :) As a fellow lover of tropical themed worlds I had exactly the same debate with myself as you. In my case I have not touched TS4 in over two years and it is no longer installed on my computer. Fairly easy to fix but then I considered the content I have with TS3. So for now I am sticking with the one game but I will say with this new pack the dev team have upped the standard for TS4. Not enough perhaps to solve all the things I find off putting about the game but definitely a move in the right direction.
