So good place to start with Ace Combat? Own X1, PS3, PS4.
unfortunately, your options are extremely limited
you can play assault horizon, but that is...not exactly ac at it's best
infinity is f2p on ps3 and acts as something of a 'greatest hits' compilation of various missions, but you have to deal with some pretty intrusive monetization systems to get to the good stuff
the definitive games are the japanese version of ac3, and ac4/5/0 on ps2. trust me when i say it is worth it to buy a ps2 just for these games
the tears won't stopThey've basically brought back a dream team for the project
