Ok let me explain some things:
1. Yes, we are on the Starmaker page, imagine people talking about other game here, of course people is not going to talk about RS2 here.
2. Starmaker is free here on itch, RS is available only on steam and patreon, and RS2 is in development. So once again, of course those won't be mentioned.
3. While Starmaker always showed when going inside the Arvus patreon, it wasn't until recently that it started being featured on the patreon banner, it was always only RS and now is both. Outside of this i don't know how you see Starmaker as a selling point.
Saying this is a crowdfunded game is just incorrect, the game has grown into popularity since 1.5 but the updates were as good before and no, there were not a huge amount of people sub to patreon for it. In fact, RS2 development has been taking so long because both games are worked at the same time. And the point still stands, it is FREE, the fact users can donate to patreon doesn't make it not free.
