its a text dump though, so it might be garbled
also i might say, this is the best part of MGS series, i spend much more time in codec than actually playing the game
The pendant is a FROM software internal reference to earlier games with no known use outside of feeding it to Frampt.
NetHack Available for virtually every device you can imagine, for free.
An ASCII based (with graphic tiles as a possibility) where you have to go down the Mazes of Menace to retrieve the Amulet of Yendor for your god.
It's the most representative game of the roguelike genre, featuring permadeath, 13 choosable roles, and infinite replayability. It takes a couple of days to know the basics, but a lifetime to master. It's not uncommon for people to take up to one year at least to be able to ascend (finish the game, it refers to the ascension you have to make to offer the amulet to your god) a single character, let alone the 13 roles. It's often recommended for most people to spoil themselves as much as possible to stand a chance inside.
I'll try to bring up some different ones:
Riddick: Escape from Butcher Bay
The first game by the infamous Starbreeze. A stealth-action game that alternates between (some of the best) hand-to-hand combat, shooting, and stealthy stuff. For a game from 2004, it has a bunch of really interesting features and gameplay innovations not seen at the time. The story is a little lacking though. Unfortunately it cannot be bought on Steam, only GoG. Probably best to play the remastered version packed in with Assault on Dark Athena.
Escape Velocity: Nova
I never hear anyone talk about this one, so maybe it could be interesting to cover. Its the most recent game in the Escape Velocity series. Originally only for Mac, the game is a sandbox space exploration game, similar to the likes of Wing Commander but isometric. The combat is similar to Asteroids or Galak-z, with the story playing out in a "choose your adventure" style. There are a lot of cool concepts in this one, such as interlocking quest lines and random events occurring in space or on planet. There are 6 major campaigns to play through, and a few minor ones with a bit of meat in them. One of my favourite parts is the galactic war playing out in game. If you jump into solar systems on the front lines there is constant fighting between both empires, with reinforcement fleets jumping in to feed the further conflict. Not to mention pirates who set traps for the player and mysterious races on the outer-edges of space. Its not cheap, but it is Shareware, so you can play the whole game for 30 days for free.
There's also this two WIP projects that seem very interesting, one is a port of Morrowind to Skyrim's engine, the same way of Morrowoblivion IIRC, and the other is an port to a open source engine.
I wouldn't recommend you trying this two today, since they're on early production and aren't nearly as complete as Morroblivion but for some reason you want to try this ones into the future (a long future), they might be better choices.
I've been using a similar app called Forest- it's a Pomodoro timer at the core where you plant trees on your patch and it grows for the time that you set to study/work for. If you use your phone in any other app other than the timer screen, your tree will die and not grow. You gain coins and get achievements, unlocking new trees for your patch. Plus, there's an option where you can use your in-game coins to fund the planting of a real tree which is really awesome. https://www.forestapp.cc/en/
We just released our first indie android game - NUMBALA. It's completely free (and without ads). We want to help kids understand math but in a fun way :) Here's the link: https://play.google.com/store/apps/details?id=com.Neurodio.Numbala_Free
I googled it and this came up on Amazon.

It's got very good reviews but also there is an abundance of level design books in the suggestions on the page below. I can't speak for any of them but one of them is bound to be good.
