You made the right choise. I mean sure Wii U got mario kart now and zelda coming....but that's only two games and it's clear that ps4 and xbox one will get more games than wii u.
Good games for ps4? Well it depends on what kind of games you like :/. I myself like zombie games, shooters and driving games. The Last of US, Battlefield 4, Gran Turismo 7(coming)....watch dogs was ok too. And well actually all the first party games are good: killzone, infamous, little big planet(coming) and so on. If you like sport games then Fifa and NHL ofc. But just to remind you, the ps4 cant run ps3, ps2 or ps1 games....if yiou want those, then you have to wait for PS Now to get ready. PS now is only a beta right now and available only in the US...and the prices are ridiculous.
About Indie games i dont know.
I hope you find PS4 gaming interesting and fun :)
