So, I've decided to start modeling for Blockland. Not necessarily for posting addons and stuff, but just for the sake of knowing. Unfortunately I have no idea where to begin, nor how to start modeling anything.

What I'm asking for is a simple guide on where to start.

What programs should I use?

What's a good way to practice?

What should I model?

How 2 model?

I really don't like asking people for step-by-step guides, but that's really what I need. Maybe I'll finally understand what "lowering the polygon level", and stuff like that. I'm not asking how to model really detailed weapons or something, just some basic advice on where to start, and how to do it. Thanks!
