Just like selling a house with a garden, solo modes thrive in times of corona :)
It seems that more and more games have a built in solo mode and designers around me utilize the "solo mode by design" principle.
This mean that from the start, they assume the game will be playable by 1-to-n players.
This would also mean you would seriously consider to bin a game mechanic if it jeopardizes the solo mode.
Players: Do you applaud the designs that have built in solo modes that clearly fit the game and aren't thrown in just to be able to advertise it? Or the contrary, that this philosophy hurts the inter-player dynamics of a game because solo and multiplayer are 2 different breeds?
Designers: do you follow this principle or explicitely choose -not- to?
Do you agree this philosophy is on the rise or is my conclusion colored by coincidences in my network?
