They are conceptually very similar and both obviously inspired by the old CHIP-8.

TIC-80 is a bit more 'powerful' in that it's a bit higher resolution with double the sprite count.

The most substantial differences:

>PICO-8 has its own BASIC-like language

>TIC-80 is programmed in Lua or JS

>

>PICO-8 is commercial software, costs $15

>TIC-80 is open source

Pico-8 is restrained by design.

> The harsh limitations of PICO-8 are carefully chosen to be fun to work with, encourage small but expressive designs and hopefully to give PICO-8 cartridges their own particular look and feel.

It can be a little frustrating at first, but if you focus on the other important elements of a good game it can be really satisfying.

In addition, there are some people doing some very cool stuff really pushing that limit as far as possible.

Just to cherry pick a few. Personally, I like the restraints.

To add to the others, Pico-8 definitely uses a modified version of Lua 5.1/5.2.

PICO-8 may be commercial software for creators, but players can play PICO-8 games published via the web app for free.

The author, "zep" (of lexaloffle games), is also a wonderful human being that goes out of their way to support people who buy it / play PICO-8 games and deserves every penny for it.

While I hope they some day consider open sourcing PICO-8 so it may live on, for now, it provides them with meaningful income and lets them actively develop it, which I wholeheartedly support.

The author is actually Zep. Lexaloffle is the company.

As ungzd already said, PICO-8 doesn't use its own language, but instead uses a slightly modified version of Lua

PICO-8 uses plain old Lua also; the editor downcases everything on save which is why it seems case-insensitive.

[springogeek]

It also adds a couple of convenience language features and a simplified API, which is why it appears "BASIC-like".

[boomlinde]

The PICO-8 language is just Lua with some minor syntactic sugar.

It's also worth noting that TIC-80 has a $5 "PRO" version; the free (as in no cost) and open source version is basically shareware.

[Nullabillity]

From the README:

> For users who can't spend the money, we made it easy to build the pro version from the source code.

So the pro version is still FOSS, their builds are just not gratis.

[jacquesm]

That's a nice mixed model.

[ungzd]

PICO-8 uses Lua too.
