The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games. It provides practical instruction on creating world-class games that will be played again and again. View it here. A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games. With special focus on those developers with small budgets and limited staff and resources, this book is packed with tangible recommendations and techniques that you can put to use immediately. As a seasoned professional of the indie game arena, author Joel Dreskin gives you insight into practical, real-world experiences of marketing numerous successful games and also provides stories of the failures. View it here. An Architectural Approach to Level Design This is one of the first books to integrate architectural and spatial design theory with the field of level design. The book presents architectural techniques and theories for level designers to use in their own work. It connects architecture and level design in different ways that address the practical elements of how designers construct space and the experiential elements of how and why humans interact with this space. Throughout the text, readers learn skills for spatial layout, evoking emotion through gamespaces, and creating better levels through architectural theory. View it here.

I'm still not entirely sure I believe that it works

The following Epoch program now compiles and executes:

// Simple implementation of a singly linked list holding arbitrary data

type listnode : list | nothing

structure list :
T value,
listnode next

prepend : list ref thelist, T value
list newlist = value, thelist
thelist = newlist

append_recurse : list ref thelist, nothing, T value
list newlist = value, nothing
thelist.next = newlist

append_recurse : list ref thelist, list ref tail, T value
append_recurse(tail, tail.next, value)

append : list ref thelist, T value
append_recurse(thelist, thelist.next, value)

next : list ref thelist -> listnode tail = thelist.next
next : nothing -> listnode tail = nothing

checkvalue : list ref thelist, T expected
assert(thelist.value == expected)

checkvalue : nothing, T expected
print("Unexpected end of list")

dumplist : list ref thelist
listnode nn = thelist.next

dumplist : nothing

entrypoint :
list numbers = 1, nothing

append(numbers, 2)
append(numbers, 666)
prepend(numbers, 0)


assert(numbers.value == 0)

listnode node = next(numbers)
checkvalue(node, 1)

node = next(node)
checkvalue(node, 2)

node = next(node)
checkvalue(node, 666)


This is the first implementation of a generic data type container in Epoch.

Suffice it to say it took a monumental effort to pull that off, and I am thoroughly exhausted. The fact that it's 4 AM has nothing to do with that.

Lots of cleanup needed now... there's a host of ugly hacks and leftover cruft floating around the code, and it'll take some time to improve things to the point where I'm happy with the implementation of templates in the language.

The flip side, though, is that I built a working implementation of templates in what amounts to a couple of weekends of work and a spare evening, so I'm pretty darn happy with that.
