Rock God Tycoon is a simulation game with a unique concept/setting. You start as a band of nobodies who make terrible music, slowly becoming a world renowned band.
There are a wide variety of game mechanics at play. Band members have traits that can be both positive and negative. Tension between members must be managed, while also focusing on building solidarity among them. Training your skills and buying new equipment is another important aspect.
For music, the game uses a fairly in-depth process. There are the early song writing stages, followed by rehearsals and recording, culminating in releasing your music. Record contracts play an important role, often having strict guidelines around touring and album production. One of the most unusual features is the ability to actually create a song. There is a relatively simple track creation tool, which allows you to drag and drop pieces of actual instrumentation and create a song out of it. Afterwards, when performing the song, you can actually play the track in a Guitar Hero-esque mini-game. All of these elements make Rock God Tycoon a game that stands out from your average simulation game.
As for the negatives, they generally come down to pacing. The game progresses slowly and can get repetitive due to how long many things take. The game itself is also casual and relaxed, often to a fault. The huge number of mechanics are a great start, but they are all fairly basic and lack depth.
Ultimately, Rock God Tycoon is a good simulation game with a unique concept and decent execution. The main issue with recommending it is that many fans of simulation games may find it too simplified and shallow for their taste. For anyone that enjoys a more relaxed experience, this is a solid game.
