Of course I have never played STO, I have never seen their 20 euro ships, which are the best, oh and new ones are being released all the time, the only way that would be cheaper than FFXIV would mean releasing new ships no more often than every 3 months. Then lets no forget the lock boxes, keys for STO cost about 10 euros for 10, you can need over 100 to get the exclusive items from them if you are unlucky.
Large exp boost almost 9 euros
Lets not forget the fact we have 2 characters one FED one klingon, and the ships can only be used with their respective faction, so a new klingon and FED escourt comes out, that's about 40 euros straight up, then 2 months later 2 more come, better thats another 40 euros 80 euros in 2 months is really cheaper than FFXIV.
You pay more to be effective at F2P games than subscription there's the proof.
Here is the link to the c-store for STO for you to ponder on.
