For edits whithin a page, I use inkscape. Both program combined have covered all my needs until now.

I don’t know so much about EGS, but probably some of the following (most of which I don’t use very often, I hope I recall correctly)

• Refunds
• Family sharing of games
• Sharing games for other local users
• Being able to lend games
• Remote Play (with friends)
• Remote Play (stream for a local machine)
• Linux support through proton
• probably more?
