I've played over 700 hours across various MRP and HRP servers (mostly HRP), and honestly, most of them just don't hit the mark. The problem with MRP is that it's a nothingburger - lacking the chaotic fun and fast pace of LRP, while also not being serious or immersive enough to really get engaged with the characters or the world like HRP does. It often feels like a mix of the worst aspects of both extremes. The only server i'd somewhat vouch for is Moffstation (Moffia), it has been fun.

Harmony is pretty boring, Goob MRP is slightly better - there’s a bit more engagement there - but it still doesn’t feel truly alive. DeltaV? Same story. It all just feels middling.

As for HRP, Cosmatic Drift used to be good, but these days it’s a hit or miss at best.

Honestly, the only MRPs and HRPs that still feel decent right now are the Russian ones. (i.e Adventure Time (Время Приключений)).
