It's not easy coming back from this, you only get one first impression. But with that said, they seem willing to eat the whole humble-pie and probably had to wash it down with some bitter pills. So if they're genuine and do it right I wish them nothing but luck.
Game is dead and they should abandon it and move on instead of continuing to put their life savings into this thing. They need family members and loved ones to tell them that enough is enough and that they should shut it down permanently.
the idiotic round based game modes,
the class based bullshit with segregated weapons,
the ultimate abilities,
and lastly the loadout system with unlockable perks and guns...
it just completely went against everything the first game stood for.
