no, funzcentre and funzsquare are not the same. just happen to have a similar name. funzsquare is located at far east plaza while funzcentre have several outlets (amk hub, orchard central, vivo and 2 more cant remember)
if you want to buy cheap console and games. go qisahn (far east shopping centre) or wargames (amk jubilee). these 2 shops are probably the lowest prices you can find in sg.
can go their websites see see look look and do some comparison.

just take note, most of the time, there is no need to buy a game at its suggested retail price (SRP), can get cheaper elsewhere.
just to give some examples, the evil within SRP is $74.90 , driveclub SRP is $69.90. can easily find shops selling at $65 odd and $64 odd respectively.
