Akiba's Trip is basically a giant scale jrpg based on Akihabara, the anime and video game mecca of Japan. Basically, if you haven't heard of Akihabara before now, then skip this game because you'll not understand all the classic anime and Japanese pop culture references and tropes here period.
Whilst the game isn't exactly perfect, with some crash/bug issues and even some technical problems such as frame rate loss on the PS3 the game provides enough entertainment and things to find and explore that most of the problems seem minor by comparison, exploring an accurately mapped Akiba is an amazing experience, many of the famous stores like Gamers, Club Sega and many others are accurately recreated, as well as the multitudes of maid cafes and of course the varied people walking around town ranging from the typical 'average' people to maids and school girls. Personally, the game would be even better if you could actually enter all the major buildings and explore them but sadly all the stores you can visit just have store front menus, but still some of the menus have cute or well known characters such as Dejiko (Gamers Mascot) to greet you.
The combat system is rather similar to the Kingdom Hearts series, but with the twist of actually stripping down your enemies so the light of the sun will destroy them, basically the enemies are vampire types which have infested Akiba and its your job to protect the town, add in tons of side missions and a massive amount of customization both in weapons and clothing, and you have yourself a nice little game, unfortunately like I mentioned earlier in the review - unless your an otaku or anime fan, most of this game you're not going to enjoy or understand - and that is the major problem, but if you are the otaku type expect to see huge amounts of popular Japanese culture right up close, even many references to popular characters - expect to see advertisements, I saw adverts for Hyper Dimension Neptunia, Genshiken and many others and as you explore, the feeling of exploring and hoping to find the next 'cool' areas makes the game so much better.
