Fortix 2 is a great casual game that acts as a great sequel to a great casual game, Fortix. Should you buy it, though? I say yes, but consider the flaws before you decide, because it is priced fairly high.
Flaw #1: Content
For a $10 game, it does not offer much content. It is a very short game. You can plow through it in just a few hours.
Flaw #2: Difficulty
This is arguably an easy game. It can be difficult to beat certain levels, but the bulk of the game is very easy, at least for me.
Flaw #3: (Lack of) Story
There really is no story to this game that I can find. It is purely gameplay. That can be a flaw to some, but I actually was not interested in a story, anyway. I bought the game because I like the simple gameplay found in its genre. Line-breaking games are just so addictive that I can justify spending $10 on one, but not everyone will be as amused as myself.
Overall, I say get the game if you liked the original. If you have not played the original, get it, because it is only a dollar.
Another thing to look for when browsing PC games is the system requirements. There are really 4 things you need to worry about: RAM or memory, processor, video card, and finally, the hard drive space. Memory can be upgraded fairly easily, and it shouldn't cost much. We recommend having at least 1GB memory, 2GB if possible. Your processor needs to be fairly modern, and a Pentium 4 probably won't cut it. We recommend a 1.8Ghz Core 2 Duo or better. Your video card should support DirectX 9 (or higher) and have a minimum of 256mb memory attached to it. We recommend 512mb or greater. Hard drive space is subjective, but we recommend having a fairly large amount of space. You could settle for as little as 40gb and be able to play most games, but we recommend having 80gb or more space to make sure you have room for multiple games at once. Most PC games don't run straight from their disc. They usually require an install process, and most modern games require around 8gb of free space to install.
PCs are the ultimate game console, because they can be upgraded, and they will never go out of style. PCs can also play most old game systems through emulators, so if you lose your Playstation, you can just play your games on your PC. You can also play classic arcade titles and have infinite coins!
A lot of people complain about having to use a mouse and keyboard to play PC games. This isn't a requirement, fortunately, and we have what we call gamepads or joypads. Yes, we can use game controllers! We can even use Xbox controllers! That said, it's not as plug-and-play as a game console, and some games simply will not work with your joypad. Fortunately, Steam tells you if games support controllers, and if your favorite game doesn't support them, you can map the controllers to keyboard and mouse controls.
Just be careful when buying PC games. Read reviews carefully. If a game gets a 1/5, don't buy it. If your PC is a cheapie, don't expect modern 3d games to work. Read the system requirements very carefully. If you don't know anything about your system, you can find help in the PC Stuff forum.
