Look at the video in the link. Heavily inspired by HeroQuest, note the decor. However, it doesn't follow HQ at all. If I really want to match the experience of HQ there are much better computer games out there with much better graphics for free ... Basically, if you want to charge me to play you best put some work into it!
Honestly I was more than impressed with the gameplay I feel like its one of the best electronic hero quest experiences I've played to date. I've had a lot of fun with it. That said I'll try out the free game you suggested as well.
