I think hacks are just a tool. In my opinion, a player isn't lazy or inferior because they choose to use hacks.
What counts is the creative thought behind the process.
"Thought > Process" for me.
Any artist would know that hatching the idea is what truly requires work.
For me, hacks are simply a method to produce the result faster.
Because if I've got a great idea in my head, I really can't wait to put it together in the game.
And imagine running around in a server, and seeing a massive swastika.
Even if it were made without hacks, it's still a piece of uncreative filth.
That said, I do admire non-hacking players that surpass 'hackers' in building ability.
Too legit to quit. In a pretty awesome way.
Hax made stuff like ecrider's insane projects easier.
True, without hax it might have been prohibitively difficult, but not impossible.
I fall on the side of the argument that hax are fine for some things, but really, Minecraft as a "construction simulator" is made less by the fact that hax allow users to do things counter to reality. I wouldn't be near as proud of Shadowmarch as I am if I had used any hax.
Still, for something like this, the impressiveness of the project is astounding. Well done!
