First of all it's a new game called "Freebuild". We have the newest engine, and we have made enough modifications to call it a new game.
Retail is a new and improved Alpha! What's wrong with new and improved?
We are not stealing ideas from retail; we are doing things that we've been wanting to do for years, and that Eric happened to do in Retail. They were community ideas and Eric simply got to them first.
You are using old screenshots, not to mention this is our first alpha release. This means that our GUI is by no means done or as pretty as it could be, but we are getting to it. Similarly, our decals and models aren't new; most of them are the same as stuff from retail but that's because we simply haven't gotten around to it. This is our Alpha release, not the final version (not that that will change your opinions, or your insults).
We are not striving to compete with retail Blockland. Should that happen, then, very well.
Also, the game is free. We are making this in our spare time. Badspot had money to make, we don't. I am not bashing his decision, just pointing out what we've done simply to do it, rather than to make money.
Also, I did buy Retail, I do have a key. I have played. I don't have all that much against Badspot; in my experience he's been more helpful than most of the community.
Thanks to those of your, like Jellycaek, who seem to be sensible people, and won't skip to judgment on something you've never even tried.
