I have so many mixed emotions about this. On the one hand, a Bioware RPG (plus) about Sonic and friends (also plus), on the other hand it's a DS game with all the limitations of the DS handheld (con), and with scrapped sequel plans that means you have a cliffhanger ending that will never get resolved (also con).

Reading the comments it seems the game is also tedious to play (major con). I feel like I'm missing out by not playing, but I feel I'd probably prefer to miss it than play it.
