I'm very surprised at the reactions or comments made by people who tried out Shards Online. Do they even know that the game is still in Pre-Alpha?
Yes, it's playable but it's not the complete game. Remember, Shards Online is going to be a moddable sandbox online role-playing game where players can create or start or manage their own Shards with their own rule-sets, stories and live content.
If you played Shards Online during the Open Preview Weekend then what you saw or what you played is just a very small portion of what the game is.
It may not have the best graphics but the potential of the game is great because it's going to be a real sandbox online role-playing game.
Just imagine yourself running your own Shard or server with its own Rules and Story. That would be awesome.
Anyway, based on the comments or reactions made by the people who tried the game, I think Shards Online is not fully understood by many of those who tried it but that's just my opinion.
