[quote name='Gothic Walrus']Is the game worth getting if you don't have Live?
I did enjoy the demo, for what that's worth, and I do have a history of putting more time into games like this than I should (especially the Pokemon GBC game).
The problem: I've got Gold right now, but only until the beginning of August. I'm going to have to cancel then because I don't have the money to pay for it right now. I'm interested in the game, but I'm not sure if getting it without multiplayer is the best idea. How long before I get through all of the challenges and get bored with the single player?
One alternative would be picking up something for the DS (maybe the Marvel card game) for cheap in the B2G1 sale.

IMO, the single player is better than the multiplayer. You need to unlock cards and decks by playing single player. It's fun getting more powerful cards for each deck. The multiplayer game offers nothing other than achievement points (and bragging righs). You play one of 10 decks over and over again. They may have differences depending on the player. But because you can only add unlocks from a list of 15 predetermine deck specific cards (you can't take any originals out), the variations are almost unnoticeable in 95% of matches. It gets boring playing against the Black/Green elf deck 10 times in a row.
Every game goes like this (I play Mono Black, R/G/B, or R/G/W)
1. Identify deck I am playing against. (I'll assume Black/Green because it appears to be most often used deck)
2. Save Terrors, Incinerates, and Shocks for Elvish Champion
3. Trade creatures early
4. Gain control of game and win
