I'm thinking of buying this game, though for me it is painfully expensive, you, as those who bought it, can tell you what kind of sale there is a discount for it (summer, spring, etc.) and how big it is. And I would also like to play it with my friend, so I know that there are two types of cooperative in the game, one with a common screen on one computer, which does not suit us because we are in different countries, and the second with DLS, there you create your own room and the players join you, and so in the descriptions of this dls it is said that the players will not influence each other in any way. That is, if we reach a certain chapter, there is a battle with the boss, everyone will win their own? that is, we will only see each other and communicate on ds, but we will not be able to complete quests with a joint effort? please answer

p.s. sorry for the mistakes I am just Russian and write through a translator, I asked the Russian wiki about this game, but it is "dead"
