I`m building a couple , its got a good footprint size and reasonable payout although for me at least , a poor collection cycle . I`d be interested to hear why we got the other clock last month as a defense building , was that supposed to be this one , was it released in error ? I`m actually susprised we got an LTB at all , with the re-release of all the old ones I thought that would have been a perfect excuse for Gree to not bother putting a new one out for a while .
