Also, depending on the Game Master and the players preferences, most of these cards can be put aside and ignored.
The Skill Cards are more for players who want structure in their campaign. If players don't want to use skill cards or rather go with more rounded abilities that is fine, it's up to the GM to decide what is within reason for what powers and abilities players have and which stat to roll for players decisions.
The Content Cards serve more as an extended rule book than necessary for gameplay. It mostly covers traditional elements from the actual Sonic games and such.
For example, in almost every Sonic game, there's item boxes, or "monitors" as some call them. They're like the ?-blocks of the Super Mario game and these item boxes have an icon to indicate what kind of power-up you have.
So, I made Content Cards that cover various power-ups from the Sonic games and adapt them to my Sonic RPBG. This way if a GM has the players come across soemthing that is expected from the Sonic game, the GM could show the player the Content Card for reference.
Having lots of cards may make it look complicated, but if anything, having a whole bunch of cards is to make the game more simple to follow and not "Here is Dungeons & Dragons Fifth Edition. Read the whole thing if you want to play with us/"
