Besiege Review (Ampoulgon 87)
This is the most underated game I've ever played. theres a relitively small selection of blocks but they combine and interact in extremely satisfying and emergent ways. and with logic blocks that give finer control of keyboard inputs, the posibilitys are endless. it is truely the best engineering-sandbox I've played, both in complexity and the simplle presentation of that complexity, so its never overwelming. its got a ton of real-life physics as well, from tourqe to litteral rocket physics. so no matter the skill level theres plenty for you to try. and thats just the sandbox, the campain levels are full of humerous, unuiqe, and challenging levels that start as subtle tutorials and end with you making machines far more complicated then you'd expect. (I also highly recomend challenging yourself by trying to beat every level with just one machine, its hard but fun!)
TLDR; simple comcept/blocks, very complicated but easy-to-follow emergent gameplay. game gud. also enemy physics are funny lol.
