This is going to be a tough one. I know no one who's really pumped to see this, yet I know it's still going to do pretty darn well. Going to guess $60 million, a hair bit lower than the original ASM did.
@yami4ct: Yeah, I know Mega Gengar has a crazy good ability, and I'm assuming the stat buffs are extreme.
It'll take time to see which megas shake out. Most provide interesting alternate options to standard sets. There's a big discussion on mega viability on Smogon right now. Some are sure bets to see play, like Gengar. Others are not as sure. Pretty much across the board stat buffs don't always outweigh the bigger stat buffs a hold item might provide.
For those of us up there, is having a Mega on the team really necessary? If it's worth it I'll make a slot but I'm not 100% sure it'd make that much of a difference, but then again I haven't used any of them.
Depends on the Mega. In general, it's useful to have one. A lot of Megas like Gengar and Blaziken have obvious advantages over their base form, even taking losing an item into account. Basically, yes. It's worth making room for the one mega you're allowed to have on a team.
I don't generally buy used for new games. Keep a good enough lookout, and you can get great deals on new copies of recent games within the first month or two if not on preorders. I do, however, rent a ton of games. I don't like keeping games around. I don't collect. The only reason I buy games is if it's exceptionally long, really cheap, or I adore it and want to own it. The only games I collect are the ones I really enjoy. The only used games I buy are ones that are so old, it's near impossible to find them new.
