I'd pay a lot for a good reimplementation is syndicate. It was so good in its simplicity and so good in controls.

Syndicate wars was both an improvement and a failure at the same time in many ways unfortunately.

Have you tried https://store.steampowered.com/app/268870/Satellite_Reign/ ?

Yeah, I tried it for quite a while and found it really disappointing. Maybe I fail at playing it, but it seems to move between syndicate-style global map which is OK and restricted missions which are super slow, super annoying episodes where you get kicked back to the beginning for every stupid mistake. You just can't afford an open fight at the beginning and it's so slow I couldn't progress to real upgrades. It basically turns into a stealth game where any detection means you're swamped by new units and dead.

This is much different from syndicate where if you messed up, you just faced a bigger fight. You could die or survive, but it was a fair fight without sudden reinforcements.

To be honest, I bought it but never found the time to actually play it. I loved Syndicate on the Amiga, thought. Some time during the 2000s, I tried Syndicate Wars, but its crude 3D engine was a real turn-off.

Yeah and it's not really that good.

Check out Satellite Reign. I found it a very fun game that considers itself the spiritual successor to Syndicate.

What I find the most impressive about Syndicate is the action phase was only 16 colors.
