Some rpg systems have skills list for player characters. Examples of these are 3.x and 5th edition Dungeons and Dragons, GURPS, Champions, Basic Role-Playing, and quite a few more. Whereas there are some older games as well as some modern OSR-based games that do not have skills inherently built into the system. Non-skill based systems abstract it out through the use of ability checks or even using character backgrounds – something Dungeon Crawl Classics does. We talk our preference.
Race as class in role-playing games, it goes back to Basic, Expert, Companion, Master’s and Immortal’s (BECMI) sets of Dungeons and Dragons. It is also part of many other rpg’s like Dungeon Crawl Classics, Lamentations of the Flame Princess, and many, many, more. Like two guys sitting at the lunch table, we banter a bit about this topic.
