Words of wisdom I was once foolish enough to ignore. Seriously people, we don't need some corruptable, shoddily-made trading card system to show off everyone's e-peen. Spend your time thinking about a good idea to make, then make it.
Don't you realise that DrenDran makes a whole new gamemode?
A gamemode about trading and collecting.
It will give Blockland a whole new feeling, similar to the "Steam"s achievments.
It will show people add-ons they might never had heard of.
Add-on creators are honored for their hard work.
etc. etc. etc.
Don't try to discourage DrenDran from creating something for Blockland.
