The other game will offer all the content these overpriced expansions give us, but with a the price of a normal game. I would rather pay £40 and get all of this, instead of gambling on the expansions, especially after seeing all the broken promises from elite.
We'll see that if and when it happens. I bought SC before I bought ED, since that time I have 'played' SC for maybe 3 or 4 hours, there is only so much fun to be had walking around my hanger and playing arena commander, I update it now and then to check how things are coming along, not a lot has happened, and more importantly the game still runs like crap (I'm really not sure they picked the right game engine). If I was offered a refund for SC at this point, i would probably snatch their hand off.
By comparison I have had hundreds of hours of gameplay in Elite, and whilst it is far from perfect (and I've picked my faults with it), it is very enjoyable and I feel I have more than had my moneys worth from my initial investment.
At present, Elite feels like vanilla WoW to me, it is a fun base game and it will improve with each expansion.
