This thread reads like the SWJFO threads:
"Combat looks rough"
"The main character is ugly"
"This is going to flop"
Game came out, good reviews, people loved the game and over 8 million copies sold in 6 weeks.
You're not wrong, but at the same time, JFO had less of an initial 'rough' look to it, and even then people were skeptical until more previews started coming out saying that the game felt good AND Star Wars-y. And even then, people still criticized the combat and some of the bugs/jank it had - which did make its way into discussion from the press at release.
Avengers, so far, has botched its initial reveal (variably, depending on who you ask), and I have not seen super-positive press footage/discussion regarding it - granted, we've got 6 months to change that mindset, but we'll see.
It'll sell just fine, no question, but for a GaaS, I'm not sure it'll have legs.
