Was thinking of creating long campains, for example the kill team cut off and stranded on a planet continuing there objectives while exploring the world they are on.With a random encounter %check per type of planet could spice things up.I'm also a d&d vet player the idea of having a %roll on weather and encounters could be fun..what do you guys think??

Idea sounds good, theres a good reference for doing this in extraction. It bases this off of how fast the characters are moving and how close the imminent invasion is.

I would make the encounters as non combat based as possible to increase RP potential. For example they come across some potentially dangerous Dark Age of Technology items, or maybe a group of refugees led by a fanatical cleric, perhas an indication that a Space Marine Kill Team has been onto the planet previously.

I think it's not only a good idea, I think it's near mandatory. Either that or I played too much Rolemaster myself.

Since I started out in rpgs playing AD&D , I consider random encounters pretty much standard operating procedure. If I don't have tables specially prepared for a particular setting, I just go with a 10% chance per hour/half-hour/15 minutes(depending on the setting) of an encounter, and if I get a "hit" I make up an encounter guided by the roll of a d10: the lower the number, the more mundane the encounter, and the higher the number the more unusual.

Depends. Unless you're willing to happily accept every encounter on your table to be entirely appropriate and OK to arrive every time you roll it (including three times in a row!) AND happy to kill PCs with random encounters; don't use them.

There's no point having a table that you ignore, after all.

I don't use them, myself. PCs might stumble onto NPCs or vice versa, but I'll have an idea of what the encounter is specifically, instead of having to derail my party with 2d6 genestealers.

Sometimes charts are useful to roll up before the game to give you inspiration. But overall they can seem somewhat contrived.

Sound like a good idea thx i'll keep that in mind.
