Thoughts on Hunt the Wumpus Development Process

A few months back Abhi, Eli and I decided to work together on a project. The objective of this project is to develop a text-based, Ruby version of a game called Hunt the Wumpus as a group exercise in order to explore what it would be like to work collaboratively on a programming project and to develop our team-working skills

Hunt the Wumpus is a classic game originally developed by Gregory Yob and was suggested by Chris as a good project for us to work on.

What we've ended up with a few months later is a working game, but with two versions of the code-base:

What should we build?

Rather than just picking an idea and jumping right into writing code, we think it's a good idea to spend some extra time up front to explore several different ideas, compare them, and choose the one that ranks best based on the following factors:

• Will the project be useful to at least a small niche of other developers?
• Can we get to an MVP within a reasonable amount of time (maybe a month?) with the limited amount of time we each have available per week
• Is there room for continued growth of the project once we reach an MVP?
• Do the technical steps involved in building the project rely mostly on things we've already learned (thus allowing us to practice and improve our efficiency with our current skillset), while also offering a good challenge for each of us to learn a few new things?
  • These new things could be: more advanced features of the Ruby language, more advanced OO design concepts, or even just having to dig into the documentation for other libraries
• And

Tell us a little about your background.

I was an SEO guy when I started dabbling in web development. The digital marketing company I worked for did a bit of design and development as well and I always found myself trying to sneak into projects that required me to write code. It was all front end stuff at this point: HTML, CSS, a little jQuery. I was terrible at it of course, but it was way more fun than keyword research or link outreach.

I kept looking for practical ways of practicing my new hobby, and because I worked with spreadsheets so often, I started writing Ruby scripts to automate all the repetitive tasks I dreaded doing manually. Eventually, I started digging into Rails so I could build some ridiculous app ideas I had that were clearly never going to go anywhere. They didn't, but I learned a lot and eventually decided I wanted to leave the digital marketing world and be a developer.

Lots of books, tutorials, blood sweat and tears later, I landed an internship with this pretty cool little compan
