Weird Worlds is another indie bundle game I stumbled upon. For a 2005 game, this is a pretty decent rouge-like space exploration and combat adventure game. After playing FTL quite a bit, it's pretty obvious where FTL got a lot of its ideas from. Much of the gameplay is very similar although the combat of Weird Worlds is overly complicated. It's kind of like SPAZ combat in some respects, but without the intuitiveness. The game does provide a combat simulator that allows you to practice as needed, but to win it's more about what equipment you have as opposed to using any real strategy.
Weird Worlds biggest shortcoming is the lack of a proper reward system since you don't really have to earn anything. You just take items as you find them or if you find the right trader you can exchange some cheap trash for the best equipment in the game. Also you are not forced into combat and can retreat anytime. Where FTL creates an environment of urgency, Weird Worlds creates an environment of casualness and I'm not sure casualness and rogue-like is a winning combination. Essentially you are given a specific amount of time to explore and collect as much loot as possible and eventually get killed or retire and get a score based on several factors.
The randomness makes it fun from an exploratory perspective, but it's not really a game that captivates for replayability.
