Pokemon Fire Red Omega is meant to be a difficulty hack. It's not flashy and it's not incredibly different from the normal Fire Red. Most of the areas, if not all of them, are exactly the same. The things changed though, are the enemies and what they use, the levels, and even how smart they are.

Graphics- 10/10: Graphics are the same as Fire Red. Which is perfectly okay, because it's just meant to be a harder version of the normal game. Also the hack is pretty old.

Sound- 10/10. Sound is exactly the same. I wouldn't expect it to be different. Even a lot of the new hacks don't change the sounds.

Addictiveness: 7/10. I liked the game a lot. Every gym fight was challenging, and I always wanted to play to the next one. Grinding in this game actually doesn't ruin how addictive it is. Certain trainers in the game give you lot's of experience, and you can rematch them all you want. When ever I was behind in levels, it took me only about 20 minutes to catch up, so the pace was never ruined. Every trainer is using something different and is a little stronger in some way, it made me always want to keep playing. The map though, is mostly unchanged, besides a few spots with extra grass. If you've played the original Fire Red, you won't find much new to look at, as far as areas go. Also the dialogue is unchanged, besides when you get free stuff.

Story: 10/10. Literally nothing changed from Fire Red. Which is better than quickly coming up with some random story that doesn't make  any sense.

Depth: 6/10 I noticed some small things I liked. When they made Fire Red, they took out some of the trainers from Red/Blue and made them weaker. In this hack, it brings back every difficult trainer. An example of this is the level 16 Raticate in the first cave. Everyone in the game has a changed team which is nice. Although besides the different battles, you won't find anything else new to do. The starters are all different, and actually aren't normal starters. That was cool for being different. The moves you learn are also changed up.

Difficulty: 7/10. Difficult is what this hack is meant to be. Everyone has increased levels, better moves, and is just stronger in general. The gyms all have max teams of 6, all the way through the entire game. Most boss fights aren't simple any more because they cover their weaknesses. Despite that, the game hands you really powerful things at the beginning for free. You can find certain trainers to rematch that make leveling up very fast. Moves that are powerful and need to recharge like Hyper Beam and Blast Burn, no longer need to charge and can now be spammed on you. Although you can abuse this too if you learn the moves. The AI is also smart in this game. An example was the poison gym. I set up Rain Dance and was ready to clear through his whole team, but suddenly he switched to an electric type and killed my team with Thunder. This also shows how a hack can be hard without just raising levels.

Overall: 8/10. I liked this a whole lot. Everything was challenging without it being unfair in levels. The parts it did jump in levels, you had spots to quickly fix it, such as going to the trainer on the island with 2 or 3 Blisseys. I was able to be challenged without it being unfair.

I think this might be the best hack to someone who wants a fair challenge, although if your looking for a hack with all new things to do, this isn't it.
