Well there's Snakewood. Looks shoddy enough (no offence to the hacker at all, but its graphics aren't great) but its gameplay is decent!
There's Skyline, the newest hack from destinedjagold, that is also pretty sweet. Super Rising Thunder is another amazing one, don't think it's been updated in a while but it is absolutely a must see if you haven't already had a look.
And of course, there's Light Platinum, our Hack of the Year. I'll be honest in that it's not my personal favourite, but it's completed and.. well, why not? :P
I'm probably missing a fair few decent ones but there's a FEW suggestions for you, at least. :P
