THECAUSE  Bought the triple suite for $39 and am working to catalog all of my collections. Would like more game centric focused features for gamepedia akin to dvdpedia which offers a menu for additional information on the current movie include bloopers, etc. Would be nice if gamepedia offered a similar menu. Also would like the ability to use plugins with the program to add functionality. Overall however, very easy to use and works well.

XPLICIT  What about a single "pedia" for all my media stuff? One application for every different kind is somehow annoying.

Come on, four apps which do nearly the same, that's a laugh.  
(Version 4.2.1)

BIMBLE  The Pedia apps are focused on their specific media types, which is why they're sold separately. Where Delicious Library has a generic template, allowing more flexibility within the same app for varied item types, Gamepedia and the other apps from Bruji have fields and options dedicated just to the type of item they track. That lets them gussy up the HTML exports and add fields specific to the media type (like whether a game is a collector's edition, and a section for walkthrough links and screenshots).

While Gamepedia is $18 alone, if you go to the developer's website they offer package deals - right now, 20% off if you buy two, $39 for three of the Pedias as a bundle, and $49 for all four.

If you want everything in one application, Delicious Library and the newer Library Pro are solid programs. If you want something more specialized by media type and don't mind having separate apps, the Pedias do a good job. Personally I like the Pedia approach better after trying several apps of this sort. I'd recommend trying them and the other applications out then making a purchase decision after that - the price points aren't very different when the bundles are taken into account.

ATGMAC  I would be more inclined to buy this and the other three 'pedias' if it was all one app. 4 apps is too much when they serve similar purposes.

FALCOBOY7  very nice app, but kidna pricey for just games

ANONYMOUS  Let's see.. that's DVDpedia, which I registered for $18 when it came out and does work well, then CDpedia at the same price, and now Gamepedia for yet another $18.

And then there's, say, Delicious Library which I thought was too pricey at $40 which does it all and some might say better.

So, why am I getting cynical about some shareware authors..? There must be a reason somewhere.. (scratching head)
