Considering what was apparently expected in terms of sales from those games (with the Avengers game likely expected to sell a lot of micro-transaction content over months in addition to the initial sales), it might be indicative of a problem Marvel based video games are now likely burndened with.
Since many of the movies made several hundred millions in dollar profit and pushed many of the characters into popularity with even a casual audience, it wouldn't be too suprising if the big publishers who got themself the license to using them expect their video game adaptations to be similar profitable.
But seeing how the movies are visual spectacles, the publisher and perhaps the audience too, expect high end graphic spectacles from the games aswell.
However as has been mentioned before a paradigm of modern video game design is that higher end graphics create a lot of restrictions for what the game can be, often resulting in very short and/or shallow gameplay experiences and time, while increasing the development costs and time.
This is the reason why currently many indie and mid sized developers are rather aiming for highly stylized visuals than high detail "photo-realistic" ones, since those can still produce a visual pretty and/or enticing game worlds, on lower hardware requirements and less need for specialized engine knowledge.
Furtheremore depending on the IP and who holds the rights to it, the developer/publisher might be under constant pressure to release the game as soon as possible in order to counter having to pay the license fee on top of the development cost by having the content released ASAP and hopefully make profit.
The primary way this pressure is reduced is if the IP holder is very lenient, giving the developer more breathing room. But this is more often only to be expected from holders of dormant or low profile IPs.
But even then there is often the problem that it's primarily inexperienced and new studios which acquire licenses in order to skip having to create a setting from scratch. This is why many movie IP based video games tend to be shovelware, produced to quickly cash in on something currently popular.
However in this case the license holder is the big entertainment company Disney, the publisher the big company Sony and the IP the Marvel comics characters who in recent years stared in million dollar making action spectacle movies, which puts a lot more pressure on every developer who would get tasked with making games based with them.
So the overall situation seems like it's destined to have developers pressured by strict time restrictions to make high end graphic based action games, which are bound to have very short run times and shallow gameplay, but also expected to be sold in illusionary quantities to make the money for both the development time and the expensive IP license back.
Essentialy in the current climate it seems unlikely that Marvel IPs could be used for many well made mid-range video games, even though those could much better support the IPs and popularize even lesser known characters, in addition to one or two high profile short but pretty looking ones.
Though perhaps, my assumption will be proven wrong and the X-men fans will profit from Sony's handling of the IP. No reason not to have a bit of optimism.
