Condensed notes on free version: It's good, but still lacks the content, nice community and features which are critical to getting the most out of a game like this. Treat it like it's a beta, which it essentially is. Probably a 6/10 at the moment, as there are still better, free games in the same genre to play. Like the original DOTA, which is pretty much identical but with the benefit of a larger community and established, functional framework. We may well revisit this title in a few months.
