I used to play RTS games like Warhammer, then got into Heroes of Might and Magic and its spin-offs like Pennon and Battle. I’ve also played XCOM 2 and Age of Wonders 4. Any other must-play series you’d recommend?
Beyond All Reason maybe?
One game that we always play at LANs is Spellforce III . It’s got a great old school RTS vibe while throwing some new stuff in the mix and there’s a free version of the multiplayer which gives it a really low barrier of entry.
For old school RTS, Total Annihilation or if you fancy something a bit different then The Settlers II (Pioneers of Pagonia is a more modern remake). I grew tired of RTS and moved on to turn-based but Stellaris is one that recently drew me back in.
For tactics I’d say Advanced Wars, Fire Emblem and Disgagea are decent shouts. Into The Breach is probably my favourite indie of the genre, a lot of strategy packed into a small game.
If you like turn-based then Civ has always been top of my list.
For old school RTS, Total Annihilation
If you don’t care about the campaign, probably the much-newer games based on Total Annihilation that run on the Spring engine.
EDIT: Yeah, another user already recommended Zero-K.
It’s not real time but Civilization is a must for any strategy fan. I personally recommend getting V and all its expansions, it’s peak for me still. Some like VI but I could never get into it.
V has the best mods too
No, Civ IV has the best mods because the game was designed to support them.
If you want to try an RTS that does something different, check out Against the Storm. It’s an RTS, but there isn’t an “enemy” so to speak. Instead, you are ‘fighting’ against the environment, trying to solve your economic and social problems before you are overwhelmed by external factors imposed by the level you are building on.
The game continues to evolve as your understanding of its various systems grows.
FWIW: It’s currently in the Humble monthly bundle.
