Have a few questions. Which is the best arcade script for under $50? Also if i was to buy a script can i use my own template?
I would recommend you to try out gamesitescript.com to its a really good script, I use it on 3 of my arcade sites.
The best arcade script you could ever get is most probably your own. I would much prefer to write my own scripts as at least my site will be totally different to the many other arcades online.
If you want something cheaper then you should check out http://www.thearcadescript.com/ its a free script I have heard that is should be very good.
