Wait, what exactly made the game bad? I liked it.
I also thought the demo felt ok. At least, it met expectations (which weren't very high to begin with).
I'm also assuming that the full game will be slightly more interesting when higher level power-ups and loot start making a difference - although that's a bit of a gamble.
...
I wouldn't say it was bad but it certainly wasn't ... worth buying I feel when there are other games that are certainly better and are more enjoyable. ...
(Apologies for the cut - but I wanted to focus on this one sentiment.)
Sadly, I don't see 3DS littered with better games. In fact I haven't seen anything on the system more appealing than Heroes of Ruin since Kid Icarus came out - so this mediocre game might earn my money by default just because there aren't any other retail games worth buying right now.
Then again, maybe I'll just save my cash and spend time working on my DS backlog instead. I've got some old Atlus titles just begging to be played, and am finally ready to start Dragon Quest V.
