From what they've shown, I'm not convinced. I remember being hyped for Disney Infinity pre-release, and I loved how Disney communicated about the game and just finding info was so much fun and it seemed like a great worldbuilder game that would have fun stories in the play sets, then when I bought it the game just had tons of things I disliked and it's solidly in the "meh" category for me. I'm not much of a Disney fan either, none of their characters besides more Wreck-It Ralph characters would be especially exciting to me. Skylanders also has tons of things I dislike and can learn from parts of Infinity. Acti should try to communicate more often, the hype Disney builds and the info they periodically reveal to keep people interested is a really great part of DI, and Skylanders needs something similar to keep people interested and keep giving us new info because there isn't enough new content in each game, and Acti needs to stop being so apprehensive about patches which they obviously aren't doing just because they don't want to pay to get them made. But I get bored of it much less quickly than I got bored of Infinity because the toy gimmick is pulled off more uniquely, setting it aside from other games, while there are other decent worldbuilders besides DI, and overall I just find it more fun because of personal attachment. The Toy Box was just too limited for building for my tastes (no water... ugh) and the Play Sets were actually fun at first but became repetitive and stayed incredibly easy the whole way through. Minecraft is still the definitive worldbuilder to me- that may not be a "fair" comparison considering it's on the PC and it isn't held back by hardware as much, but it's far cheaper to get access to the full game if you already have a PC that can run it and personally I just find it more fun(it's actually one of my favourite games ever). Also, it doesn't have a needlessly tossed on toy gimmick that Skylanders did far better.
However, I'm not going to totally write it off either. I've heard that they're offering some improvements to the toy box such as offering new game modes, and at the absolute least, that's definitely a step in the right direction. I just won't seriously consider buying it until we hear about more improvements, although if they fix more of the issues I had with DI1, maybe. The main thing discouraging me from the game is the toy gimmick. There's no real reason given for it to be part of the game- it's supposedly because you're playing with toys of characters rather than the actual characters in the game, but that's never explained in-game, so it just felt like a cheap excuse to me- and it makes the game needlessly expensive over, as I said, something like Minecraft, or LittleBigPlanet(if you can't tell from me giving the two obvious examples, I haven't played many worldbuilders
I just like Minecraft that much). Toys also waste space. I hardly play DI but I have two shelves on one of my bookcase where most of my DI figures are collecting dust(only Ralph and Vanellope aren't suffering that fate, as they're my favourites, they're sitting on my desk). Mainly, it's just not nessicary, and doesn't really add much to the experience. True, the toy gimmick isn't nessicary in Skylanders either, but it actually adds to the experience at least a bit because data is stored on the to and there's proper lore behind it(even if that was tossed aside after SA...). I don't know the source but someone on Disney Infinity Fans linked to something that said the data for new character trees were supposed to be stored IN-GAME. Not on the toys like in Skylanders. If that's true, the skill trees do not mean having toys has more of a point now(I guess it means getting new toys is more exciting because they'll actually have more unique moves?). DI toys feel like unlock keys to me more than something that enhances the game. They're fun to collect and look nice, but they could have easily been their own thing anyway, and the game would just be better without the toys. Because of the game being needlessly expensive combined with the fact that I don't care for that many Disney franchises, play sets and challenges becoming repetitive well as my love of Minecraft which is a better world builder, and the fact that Skylanders does Toys To Life at least a thousand times better I can't get into Infinity
at all.
Please note that this post was me ranting my personal opinion more than an objective critique.
