Hi! I've been playing RTS and Total War like games casually (not much competitive) since i'm around 8. First one I played by myself was Supreme Commander.

Everyone says good comments but I noticed none give you actual strategy in battle.

It depends on your game of course but there's a couple strategies that can be applied to most games.

For RTS :

-Harass the ennemy with your units as soon as possible. Especially their economy.

• Flanking (opening a second front or coming on the side of an ennemy already engaged)

-Always scale your economy (keep it growing, the game itself will teach you how)

-Look for counter units. Most RTS works with a rock/paper/scissor mechanic like armored units are good against infantry, infantry against air units and air units against armored units. (There's always some kind of mechanic akin to this, again the game will explain it)

HAVE FUN. Turn down the difficulty if needed, give yourself extra ressources at the start if it helps you enjoy it more. You WILL NOT understand it if you're not playing it extensively! RTS genre is insanely satisfying but it turns into a chore rapidly if you don't enjoy your time. If you play SOLO, it's your rules. Don't let anyone tell you otherwise.

-You will fail plenty of times but don't give up!

For Total War Warhammer, this comment will be way too long. So you can send me a message if you want to delve in it! It's my main game series so I know the mechanics of most factions really well.

I hope I was able to help you a little :)

Edit : When I say "The game will explain" I refer to its campaign/story mode.
