I figured the blog is in Spanish (since it has links to Spanish Wikipedia). Here's some of the interesting games from the database that caught my attention:
- Tecno - The Base - a futuristic FPS made in the early 2000s style, although apparently it was released much later than that.
- PaybackTime 2 - an obvious X-COM clone, which was distributed as shareware in the nineties (here's their home page from back then), released for free in 2011.
- Cosmos Quest series, obviously inspired by Sierra's Space Quest games.
- StarFight series shmups.
- A huge number of games produced by the German developer Motelsoft, ranging from Amiga and DOS adventure and RPG games to Windows FPS titles.
