Eventually. This has been precisely a bit of a flawed argument for a long time already when comparing with ED, or with many games with DLC for that matter. The problem with SC is that it has been 10 years already and that « eventually » of yours is still many years away. 100 systems, jumping, quanta, subsumption AI, farming, repair, exploration, alien races etc etc etc etc. And the pitiful bits that we are allowed to test in the mean time are still thoroughly broken after all that time.
Now, with Elite today you can buy the original base game, Horizons and Odyssey for the price of a single game. Less even if you time your purchase with any of the sales during the year. And assuming we get further DLC in the future, similarly if you wait, eventually you will be able to buy the whole lot for the price of a single game or less.
Is someone waxing lyrical about the future of SC while comparing to the current state of ED?
