If you’re not playing NimbleBit’s Capitals (Free), first off, what’s wrong with you? Secondly, you should fix that problem by reading our review and maybe even checking out the strategy guide written by the game’s developer. For everyone else, the game’s two main IAP items recently got a little cheaper.
The two things that seem worth buying in the game are the ability to customize your capital which now only costs 99¢, and infinite lives which has dropped from $24.99 to $9.99. The infinite lives thing seems pretty optional, as once you get going and have a bunch of games rolling the lives system becomes pretty irrelevant.
I would, however, think about springing for the customization stuff as you can show your TouchArcade pride with a swanky TA capital, as seen in the screenshot here.
Additionally, if you’ve got the game but are looking for more serious opponents beyond random Game Center people, be sure to stop by the thread for the game on our forums.
