Best Kept Secret - Forget the unsatisfying Diablo III
Value for money 20/10
because it is the best and most addictive and only really free* ARPG.
It is challenging but addictive and with the skills tree that has been well described as a skills forest. You will spend weeks playing and building/rebuilding your characters.
The Ultimate Hack and Slash for hardcore fans of Diablo II who long for that "Fix"
Don't be put off by the Open Beta thing - this thing has been 7 years in dev and is as far as I can tell bug free and immensely reliable and playable.
However if you want to be a geek - it is all there for you to go Big Bang for.
But if you just want to play Hack and Slash/Crafting/Leveling and love learning from your mistakes then you won't wanna miss this free* gem. Superb single player or play with friend(s) co-op and or team/guild support - however you want to play.
The only thing on my wish list is for AI companions.
*(free to play-free to win- costs for some cosmetic only avatar upgrades - what a refreshing change and you will be tempted to spend - just to support the non greedy developers - not that this game seems at all indie - but rivals the likes of Blizzard Productions in its quality - just not its greed)
