Personal supposition and true analysis
If the publishers of lspdfr want to do like the big publishers the game must leave necessarily a Friday which corresponds to the day of exit of game.
Following this analysis, if he wants to respect their February calendar on the last Friday and February 22, 2019, I remind you that this is only a supposition following the analysis.
But it remains the publishers and can release until February 28 what makes the difference with independent publishers.
In any case a huge thank you for their work.
