Screenshot Editing (Photoshop and some Lightroom)

Very helpful thread! I know this thread is a little old but I cannot seem to get any answers regarding a question I have regarding edited screenshots. Maybe you can help me?
I noticed some people take requests in the form of “paid” commissions. One woman I know of, quite popular but I won’t name drop, charges people for her to take screenshots of their sims in her game and then edit them for her clients. Is this legal considering the Sims games are owned by EA?
Thanks in advance.
