People get angry when you call something a roguelike

At the International Roguelike Development Conference 2008 held in Berlin, Germany, players and developers established a definition for roguelikes known as the “Berlin Interpretation”.

These guys have extremely strict definitions, which mean that most “rougelike” games are in fact roguelites, if you care about what they think.

There are nine “high value” factors that are more or less a requirement:

Random Environment Generation
Permadeath
Turn-Based
Grid-Based
Non-Modal
Complexity
Resource Management
‘Hack-n-Slash’
Exploration and Discovery

Plus six “low value” factors that are less important:

Single Player Character
Monsters are Similar to Players
Tactical Challenge
ASCII Display
Dungeons
Numbers

There is, as you might expect, a fair bit of controversy about that though.

If turning into a lich is desirable then it is rogue-like

EDIT: was meant as reply to another comment.

To be fair most of the confusion stems from just the stupidity of the word rogue-lite. I also believe that if you insist on using the words interchangeably - that’s fine as long as you correctly establish the context. Like first you say you’re going to talk about Hades and Dead Cells and then you bring the R-word into it. I personally get confused when I see a video on YT saying best upcoming roguelikes and there isn’t anything resembling Rogue on it at all and the author seems to be completely unaware of the existence of a whole genre. Happens more than I’d like to admit.

Nothing…literally nothing.

It’s the same thing that people misheard

Although I agree with the author of this article that the terms are somewhat muddied, even in their more generally accepted definitions, by the fact that it’s hard to draw the line for when unlockables can be considered “permanent progression”.

Although I have many gripes with the terms in general and how they’re used, I’m of the opinion that it is clear enough for there to be a distinction; if all of the unlockables in a roguelike game are sidegrades, or merely more options without inherent strength over other options that are unlocked from the start, then it still counts as a roguelike.

Though admittedly, this can be a bit blurry too… it would be pretty easy to argue that some unlockables in games like these are more powerful than other options, especially because it’s very hard to put an objective “power level” on an item in a roguelike. Also, one could argue that merely having more options makes the game easier, thus it counts as permanent upward progression.

Yet regardless, the article’s attempt to coin the term “rogues” as the all-encompassing sub-genre/game mechanic name absolutely won’t catch on, and the differentiation between the terms does have a lot of value for people trying to determine whether or not they will enjoy a particular game, even if the line can be a little blurry.

Here’s a relevant video that I enjoyed by Game Maker’s Toolkit that focuses on the main mechanical differences between the two designs, from a very broad and practical overview, definitely recommend watching it if you’re interested in this sort of thing

Here’s another tangentially related video by Chariot Rider about roguelike progression in particular, which I also found interesting, although less relevant to this discussion

Even more tangentially, here’s a fun video by Lextorias about confusing or controversial game genres (well… game genres in general) and it has a big section about the distinction between roguelikes and roguelites

A roguelike is full reset permadeath. Nothing carries over and there’s no sweeping upgrades between characters.

A rogue-lite lets you keep or upgrade something between runs, even if the character itself is perma-killed.
