Square Enix have managed to stab some monetisation into Just Cause 4 apparently as the game was recently rated for North American audience, stating that it will have "in-game purchases" on all platforms - PC, Xbox One and PlayStation 4.
Introduction of microtransactions is rather painful if you take into account the fact that not a single game from the series previously had them. The developer, Avalanche Studios, even promised that the game would not contain any microtransactions, but the latest rating boards tell a different story.
According to the Entertainment Software Rating Board (ESRB) that covers age ratings for games in Mexico, USA and Canada, Just Cause 4 will have "in-game purchases". Technically, Square Enix and Avalanche could brand these microtransactions with a different name and play coy, but their nature is rather obvious.
ESRB didn't provide any additional information on the nature of these microtransactions but the game will be rated M for Mature regardless, but it probably has to do with the game's other attributes. For example, ESRB mentioned that Just Cause 4 will feature combat with "realistic gunfire", which probably added to the age rating.
Meanwhile, PCGamesN has already reached out to Square Enix for clarification on their microtransaction stance and it still remains to be seen whether they will override Avalanche's statement that there will be no in-game purchases from before.
This inclusion of microtransactions could imply that other games that Avalanche is working on, such as Rage 2 and Generation Zero, could also have recurring revenue models. Then again, monetisation is more often pushed by publishers than developers so nothing is set in stone yet.
On that note, Rage 2 will still most likely have microtransactions as Bethesda don't seem to be particularly distressed over an opportunity to cash in a few times more after selling their game. They didn't prove to be that successful in the past though, as Fallout 4's Creation Club didn't see much success and their current plans for Fallout 76 seemingly leave a lot to be desired.
