I'm still plugging for people who might be interested in reading my Game Development Limbo blog. I can send invites, and it tends to work out easier with Gmail addresses. (Oh, and Dark Jaguar, I sent an email that bounced. Also made a post on an inspiration I got from an old comment of yours there.)
But I digress. Thought I'd leave a public thread for discussing generic videogame stuff. More precisely, what tired old conventions are you getting annoyed with? We've all dealt with reruns of block puzzles, unoriginal soup cans, "lives," and other such things. Here, you can rant about them and propose alternatives. Here's some from me:
The basic "drop a block on a switch" type: You really have to know what you're doing with these. Far too many make it a very simple journey. The alternatives that come to mind: Limited number of blocks for all the switches. Have to get roundabout methods of moving the blocks.
Inexplicable Treasure Chests: I love Zelda, but it feels off to have a treasure chest with a key poof in after solving a puzzle.
Interchangeable Antimatter Keys: Think I'd like to have something more substantial about unlocking doors, like unique keys.
Spikes and Lava: Let's try brainstorming some more original (or at least less overdone) hazards to fall on.
