I have actually played quite a bit of the LRG titles (considering my library, Im shocked at how many games Ive actually gotten to play). Here's my breakdown.
Aqua kitty - Kind of like an underwater Gradius. Wasnt too bad and you can co-op
Astebreed - Generic Shmup
Chariot - Co-op game where you are driving this weird little vehicle around. Its kind of like pulling a wagon. Platformer. Semi entertaining.
Dear Esther - You walk around and try to figure out why the character you are playing is who it is. Not really sure how to describe it. Beat it in about 3 hours.
Dragon Fantasy - 8 bit styled RPG. Not bad. Didnt delve into much cause its the sequel to the one that hasnt got printed yet so waiting on it to play the first.
Drive!Drive!Drive! - A wtf driving game. Very hard to play cause you are bouncing between layers of map.
Factotum 90 - Felt like Metal gear while being a box.
Flinthook - Generic platformer
Furi - Unique fighting game. Controls take a bit to get used to. Could have been cool.
Jotun - Probably the LRG game I have the most time into. Very different adventure style game. Was super cool although some of the boss fights will make you want to pull your hair out.
Neuro Voider - a metroidvania style of game. Didnt quite capture me.
Night Trap - I tried to like this, I really did. Just couldnt do it. You watch videos trying to keep a couple of intruders away from the group of teens.
Octodad - You are an octopus but no one can tell trying to fit into life. You can control all the legs and do weird things.
Oddworld - Very basic side scroller platformer.
Pang Adventures - Co-op game sort of like Bubble Bobble. Definitely can get difficult. My son and I played it for hours and got pretty far.
Rainbow moon - Strat RPG. Probably the best strat RPG Ive ever played. Im almost to the end of the game. Story drags on though.
Saturday morning RPG - Basic RPG. Battles are turn based but with different kinds of options than a normal RPG. Got distracted and havent went back. Was fun what I played however.
Shantae titles - Kind of like Wonder boy but with a girl who attacks with her hair. Not bad, not outstanding.
Typoman - The game that I talked to the devs about getting published. Was worth the wait. A very cool word adventure game. You spell words to do different stuff. Puzzle based.
Ys Origin - Great action RPG. If you like Ys, play this game. If you dont like Ys, play this anyhow!
