Magic : NO magic as the name suggests, is zero magic, like mount & blade, low magic is like Conan where magic is mostly ritualistic, dangerous and depends on the bargain with outsiders for knowledge. High magic is like D&D in certain campaings, with magical spaceships, floating cities and so on. On Netherese empire, everyone could use at least a cantrip.
Examples :
- No magic = Kingdom come Deliverance and Mount & Blade warband
- Low magic = Conan(games included) and GoT
- Mid = Gothic
- High magic = Pathfinder/D&D, mostly on Netherese and spelljammer campaign settings
Tech : Low tech is like middle ages and lower. Firearms are very limited and rarely used. Mid tech is anything between industrial revolution technology to modern technology with little SCI-FI elements on it. High tech is like Star Trek, where you can travel light years in fractions of seconds, teleport, terraform planets and so on.
Examples :
- Low tech = Age of decadence, mount & blade
- Mid tech = Arcanum, Fallout 1/2/new vegas
- High tech = Kotor 1/2
An game can be both, high tech and high tech like kotor 1/2 or low tech/low magic like mount & blade warband. Both are amazing RPG's. It is just a poll to ask about personal preferences.

Of course, some times the distinction between magic and tech is hard. For eg, what is the difference between SCI FI zombies to fantasy zombies? One is caused by a virus, the other, by dark magic. What is the difference between a implant which gives the power to create "thermospheres" to a scroll that teaches how to evoke fireball?
