A system for playing science fantasy adventures in the future of old is the tag line for Hypertellurians. It is an RPG that conveys its sword and planet themes well through its use of flavourful character powers that, alongside the advancement system, encourage heroic play. However, the cohesion of the subsystems does not achieve a smooth-running engine for producing the types of stories it aims to help tell.
Dread was the first roleplaying system that I used as a game master and I recently had the pleasure to be a player of it remotely. My friend wrote a scenario that was inspired by an SCP article and it was an excellent time for all involved - I even died horribly to some freaky monster and like all good monsters I cannot begin to even describe it properly. Traditionally a game of Dread uses a Jenga tower and has players pulling a block for a given action should their character be under duress or working out of their skill. This lends to a beautifully tense table that blends perfectly with the horror genre that Dread lends itself too, however using a Jenga tower remotely is uncomfortable.
