DC vs Marvel

Well to each their own, of course; both of the deck building games, Marvel and DC, have their fans; Marvel Legendary, in particular, has been reasonably well received and relatively well-rated (compared to the DC Deck Building Game).  For me, they both suffer from having a major disconnect between the theme and the play, but obviously that's a personal opinion.  For all I know, you might really enjoy one or the other, and i'd hate to have been the reason why you missed out on that enjoyment.  I've had a much better time with some of the more recent comic-themed games, is all.

I would say this, too: The Dicemasters system is a two-player duel game with a short play time, a massive roster of characters attached to each set (in addition to each character having multiple versions with different powers and whatnot, up to four versions per character), each character with their own little custom dice, and it's more or less a version of the CCG model.  The starter sets come with a handful of characters, three versions of each, two dice per character, and all of the other things you'd need to play the basic game (though I can't recommend highly enough that you get a couple of dice bags to replace the ones that come with), but the rest of the characters and variations are found in randomized booster packs.  Each booster pack is 99 cents, which gets you two cards, and two dice (one die per card, character specific), and there are of course levels of rarity and such, again not dissimilar to the usual CCG model, and honestly the 99 cent price point is pretty good for what you get, and it only takes a good handful of the boosters to really fill out your roster to an impressive degree.

Personally, I see the CCG model as a major negative, a scheme, a gimmick, but, and this is important, even with that substantial negative weighing on the game, I still absolutely love the hell out of the two Marvel Dicemasters sets that have come out and the way the game plays, and I simply cannot wait for the Justice League one to be released so I can grab that as well (the art that's been released for the Age of Ultron movie tie-in set isn't great, it looks like still frames of the cast members in their outfits, blech, so I plan on giving that one a pass, but the art on the JLA set and the two already-released sets is pulled from various comics).  The prodigious sales and demand for the game (the AvX set sold out internationally within one or two days back in the spring when it dropped and has already had to be reprinted at least once) could definitely also be taken as a voucher for the fun to be had with the play.  So if that's a hankering you have, I'd say give Dicemasters a shot.  The starter set retails for about $15 bucks, and like I said the boosters are only 99 cents per, and it's one of my favorite new games.  Plus, it's extremely similar to deckbuilding in nature; it's based on Quarriors, which was one of (if not) the first so-called "dice building" games, which involve the exact same concept as deckbuilding (in fact, on boardgamegeek, one of the genres it's filed under is, indeed, "deck building").  Except with cool, colorful little dice. : )  When I taught it to my friend at the shop, the first thing he said was, "Oh, this is almost exactly like MTG; except a little better, and with X-Men and whatnot."  His words, not mine, but maybe worth considering?

Here are The Dice Tower video reviews of the first Marvel Dicemasters set (AvX) and also of Legendary.  They don't always give you every little rule and nuance, but they usually do provide a good overview and opinion of what's going down, and Tom definitely knows of what he speaks, having played, owned, and reviewed more games than you, I, and all the rest of the people on this forum combined will see in our lifetimes.  I would encourage you to also search The Dice Tower reviews for their take on the other various Marvel and DC games; they serve as a decent touchstone to see what the games are generally like.  There's another game, as well, that I haven't mentioned called Sentinels of The Multiverse, that is highly regarded, but uses generic hero and villain characters that are non-licence (ie. not Marvel, DC, or any other extant comic property).  I haven't played it, but i've heard good things; that's another one you might do well to look up and see if it fits your fancy.
