I just saw the in-game advertisement. In the loading screen is ok because make them less boring and aren't longer with ads. In stadium stages look good, very well integrated. In characters depends of the character. In some of them are ok, in others look very ugly and almost randomly placed so character ads are the only ones that look a bit intrusive.
You can enable or disable separatedly each ads version, so if you don't want free FM you can just disable all ads.
If enabled, itt gives you up to 12FM per played (if you lose too) match in ranked or casual online matches. 4FM for loading screen ad, 4FM for character costume ads and if you play this match in a stadium stage 4FM. So if you choose a stadium stage for you, you'd get 10FM on average per match, and if you play let's say 40 matches per day then you'll earn an average of 400 extra FM per day.
I think it's an interesting way for them to earn extra revenue to keep supporting the game for a longer period of time, and at the same time it's great to see it's optional for players who may not like it. Seeing this GaaS approach of including a lot of post-launch content, both free and paid, the in-game currency, tons of unlockable stuff and now even ads it makes me think that somewhere in the future the game will end being F2P and that this free week will be a test for it.
Does this slow down the game or make the game worse?
If not I am okay with this.
No, if you enable the ads they just replace already existing textures so the performance is the same and loading times are the same.
PC version will just mod it out of the game. Street fighter is really struggling if it needs ad's in the game
No need for mods to disable the ads. They are optional, you can enable or disable them in the options menu.
They are just experimenting with new revenue sources -as many other games did before- and potentially testing the waters before potentially moving to F2P. It doesn't mean it's struggling.
Has MK outsold SF? Honestly not sure. I know lifetime series sales it hasn't. MK isn't very prominent in the Evo tourneys though and many fighters have more entrants.
Yes, if you compare the last couple of most recent entries of these IPs MK outsold SF, and same goes with the total units sold of the series.
Both Tekken and Mortal Kombat sell way more than Street Fighter because they have a stronger focus on single player content, which is what most fighting game players basically play. Even in SFV when launched with very little SP content when looking at the PS4 trophies you were able to see that more than 3/4 of the playerbase didn't even play more than 10 online matches.
