I want to save some personal info of the player and their scores, what database can I use?
And a word of warning here: Using a database for "some personal info about the player" is maybe not a good idea. Under normal circumstances I'd recommend the use of a database when the data to be stored cannot be held in random access memory because it's too large. Storing a few values like name and score in a database is just a waste of resources. Don't forget the extra complexity you have to handle as well.
