Poot Poot Poot! A mainline Bokumono game set in a resort town that wants to be more resort-y. Available for Nintendo Switch, Steam/PC, and Ps4/5. [ Game Guide ] JP release = Feb 2021. NA = Mar 2021. EU = Mar 2021.
The DLC marriage candidates do not attend festivals or wander around Olive Town. Though they move into your farm house and then visit their home areas sometimes in the afternoons, I don't know if they wander around the farm area.
So does that mean that your DLC wife/husband wont take part of the romance/dating festivals? And that the main farmer continues to hang-out with Sindy and Mikey?
It's great news that the new update has the DLC spouses being included in the festivals. I hope the game devs decide to make school uniforms, yakatas, and animal costumes for them too.
