With so many Dote 'em ups loose in the world by now, who has time to play them all? Especially when they're only in open beta testing. Best to wait until they're done enough to officially launch, then mosey on in and see what they're all about. Now's the time to hit Prime World, as after months of open beta testing it's been declared cool to fool and has actually, properly launched. It's free-to-play, of course.
Every MOBA other than Dota and League of Legends needs a 'twist' to have any hope of drawing players away from the two big names, and Prime World's packing a fair few. Like, er, a Farmville-y castle-building game churning out resources to buy hero talents. It's also got a few maps and modes beyond the typical classic three-lane Dota clone, which matchmaking regularly rotates through, from small tweaks to the formula like spawning loads of minions, to objective-based missions a bit like Dota 2's event maps.
Prime World might not give enough reasons to switch away from the MOBAs you've put so very much time into mastering, but may be worth a bash if you fancy something new-ish for a bit.
As one would expect from a free-to-play LoLalike, players can spend cash money to unlock heroes and skins and all that.
