Right now, it is only an idea.
Basically, it will merge the physics and graphics of the Source engine, and the gameplay and construction of Blockland. I'm not really sure if this would be approved of, because 1. I'm a newbie, and 2. it would end up being a mod of Half-Life 2, and not Blockland itself.
What I would love to see are things like bricks flying away in a spectacular explosion because of a bomb, people actually reinforcing their walls so they wont be flying away in a spectacular explosion because of a bomb. People destroying an enemy base in a deathmatch because they went to destroy their main support instead of just hitting the walls randomly. Being able to create a full RPG server, where land costs money, higher quality bricks cost more than lower quality bricks, and the players enforce the laws instead of the admins.
I am currently working on a flash presentation and site that will demonstrate all my goals and visions, and hopefully will be ready earlier than the year 2567.
Hopefully I wont get mercilessly flamed after I press this post button. If people think this would be worth seeing, then I will actually start developing it. If they dont, then I will go find somthing else to do.
