About Thetaball

Thetaball is an authentic digital sport with challenging, physics-based gameplay and lifelike AI. Each of the game's 256 robotic players is a distinct individual, created by a process of simulated evolution; because the bots have co-evolved within a complex physical environment -- both cooperating with and competing against one another -- their behaviors are diverse, robust, and lifelike. The end result is a game with all the challenge and re-playability of a real-world sport.

In the single-player game, your task is to field a team of robotic athletes in order to advance through a series of progressively more challenging leagues, earning as many coins as you can along the way. You can remotely control any of the bots on your team, or let them play on their own.

In the local-multiplayer game, 2-8 players choose up sides, with AI-controlled bots filling in the empty slots.

About the Engine

Generator is a specialized 2D game engine based on Evolutionary Robotics, a technique for the automated creation of simulated robots. The engine provides a C++ framework for generating populations of such robots and deploying them in a completed game. It also includes a heavily optimized, glitch-free physics module for simulating the environments in which the robots interact and evolve. Thetaball is the first game built on the Generator engine; more are planned.

This game had me at Physics and AI. To be entirely honest, I was a tad skeptical. I wasn't sure about it, and it seemed a tad wonky, but all in all its a load of fun. I play a lot of Rocket League, and this game certainly is up to par if not better. I felt myself really getting into it as if it were an actual sports game (and normally, I am not a sports fan). Pros: Amazing physics engine, very pleased with it. A bit of a learning curve that isn't too much. TEAM MANAGEMENT (although limited, still a very good mechanic) Cons: It isn't particularly user friendly at first, but once you spend some time navigating the UI, it starts to feel a bit more comfortable. The AI is very interesting. All I can say is that I have a bot that keeps ramming the enemy goalie. Usually when the ball isn't even over there. Not because he's a bad AI, hes just an A-hole.

Rocket League but it takes place in that laser hockey minigame from Wii Play The controls feel weird at first, but thanks to the extensive training mode you can get comfortable with them pretty quick. I found mouse controls slightly easier but only because the gamepad layout options were limited. Some people complained about the harsh goalie contact penalty but imo it just serves to discourage walk-in goals and gives the game a more realistic feel when playing. Personally I enjoy the amount of statistics the game gives about each bot (including its genome, which I assume is a visual representation of its AI) and the sound design. The SFX are non-invasive and there's no music so you can put on whatever tunes you want in the background. I only just got this game today but I'm sure I'll be playing it a lot in the future
