Path of Titans: It's Better Than It Looks
This game is very silly looking on mobile, but it is completely cross platform. I have three accounts because I started using the same account I had for mobile on the PC. Then my son wanted to play so I got it for his switch, and so a I could more easily play with him, I bought it on my ps4 as well.
The game is clunky is some ways. It also shines in others, like pvp.
The breakdown is that it's an open pvp dino simulating mmorpg, in that you do quests for growth and marks, growth is like xp but literally makes you grow and marks are to buy abilities and cosmetics.
The dinos in the free pack are actually pretty popular too, for their sheer speed and ability to pester the purchased ones. They also grow quickly.
If you got kids, or just like dinos and pvp, try it out.
