So, I'm new to TRPG, and being honest, this is a quite rough start. I came here hoping to play D&D, but after checking the rulebook, or rather after checking the sheer size and detail of them I lost all hope of even getting started. Regardless, there's one specific element of D&D I am trying to find in another game and that is the character progression system (sorry if I'm using the wrong terminology), or basically the posibility of turning the character into like an MMORPG character. Starting from level 1 with no skills and continuously gaining exp, new skills, and getting it to be overal stronger. Is there some rule-light game that follows that path without the extensive knowledge needed for D&D and that can be played here on roll20?
