You know what's solid? Crap... You know what takes care of crap? Acid!!!
Basically, if you are an old-school gamer who liked turn based strategy games, you'll enjoy Acid. I could even go as far as calling it sort of an RPG game, because the gameplay is very similar to that of a turn based RPG, except for the levelling up and fantasy elements.
So long story short, good job Konami. I bought this game because it was in the bargain bin and my only hope was that it would be a decently playable game that hopefully wouldn't feature tons of videos, but what I got was an addictive and fun game which I look forward to finishing.
