The Fallout series has become popular with the current generation of gamers thanks to Bethesda's Fallout 3 and Obsidian's Fallout: New Vegas. If Fallout 3 was your first trip into the post-apocalyptic wasteland, you might want to take a look at where the series started. Of course, you'll want to mod it a bit first to make it looks less like a pixilated drug trip.
Fallout has a very simple main quest, but there are tons of side quests. If your are familiar with the newer Fallout games, you'll be able to pick up the gameplay of Fallout pretty quickly. The biggest difference is the isometric view and the turned-based combat. It's like playing all the combat using VATS in Fallout 3. The story, weapons, skills, and open world are almost identical to the newer games.
Fallout 3 is actually a very faithful modern adaptation of the series. At first, I was a little sad that it was going to be a first/third-person game and not isometric. After playing Fallout 3, I got over it and learned to like quite a lot. A Dragon Age-style RPG set in the Fallout world would be pretty cool, but Bethesda did an excellent job with the newer games. And of course having them resemble modern shooters definitely helped them connect with modern gamers. It was definitely the right decision to make the games reach a broader audience.
What you need: Fallout (get it from GOG.com)
Time: Less than an hour
1. Download and extract Fallout v.1.3 patch (eng). If you don't have the GOG version of Fallout, you'll have to install Fallout v.1.2 patch (eng) first. Just copy the "data" folder into your Fallout install folder. Go ahead and replace existing files with the new ones. This patch just fixes issues and bugs in the game.
2. Download and extract Fallout NPC Mod (eng). Once again copy the "data" folder into your Fallout install folder. This mod allows you to change the armor of party members and change their combat tactics. Ian, Katja, and Tycho can all gain levels, and Dogmeat can be ordered to wait.
3. Download and extract Fallout Update Mod (eng). Copy the "data" folder into your Fallout install folder (you should be a pro at that by now). This brings back content that was cut from the original release. This cut content is partially intact in existing character dialog, and in the game's files. This won't drastically change the game; it just finishes up some loose ends.
4. Download the Fallout High Resolution Patch. Extract the files and run "Fallout1_High_Resolution_Patch_3.06.exe." This will extract the files needed to install the patch. Point it to your Fallout install folder when it asks you where to extract the files. Run "f1_res_patcher.exe" which is now in your Fallout install folder. Open up "f1_res.ini" in your Fallout install folder with Notepad. Edit the part where it says "set the screen resolution here" to match the resolution you want. I suggest going with something like 1280x720, instead of 1920x1080. The higher the resolution, the smaller everything will be. There are other setting you can tweak if you want, though they are pretty well explained in the file. Fallout will now run in widescreen, allowing you to see more of the game world. While this doesn't actually enhance the graphics, they will look better because the resolution is better. It's like magic!
