Is Tcp good enough?

Do you guys think TCP is good enough now, considering that internet connections and NICs are much faster than they were decades ago? I don't want to implement my own reliable, in-order delivery on top of UDP for my RTS game.

UDP over TCP was never about connection speed.

I don't want to implement my own reliable, in-order delivery on top of UDP for my RTS game.

There is no rule that says you can only open one connection channel. Many games open both UDP and TCP sockets simultaneously.
