Interestingly, the Internet has quashed my enjoyment of multiplayer games: so many people are playing them, there's no chance I am going to be able to compete, given that I only play occasionally. When "multiplayer" meant "lan party" or "friends come together and play a skirmish" you actually had a chance, but now? Not so much.
I really prefer single player games with a nice story and an action that's not too hectic that I can enjoy at my own pace.
This is why for me, Warcraft 3 and Starcraft were my fondest memories of playing online games. The standard multiplayer was always going to be competitive, but the real wonder was in the custom games. This was before the big wave of indie game creators, so you had a bunch of people churning out interesting and creative games with the WC3 editor. The custom games were most famous for DOTA, but you had genres like Tower Defense which blew up in a big way in the custom game scene.
You had maps like wilderness survival and troll tribes, which, if you've played Don't Starve, feels largely derivative. Footmen Frenzy, Dark Deeds, Sheep Tag, Uther Party (Mario Party ripoff), LAOP, Parasite, Mars Survival, Risk knockoffs, etc. It didn't matter if you sucked at these games, because most people sucked at them; the playerbase for each custom game was pretty small. A good time for novelty - I'm hoping reforged brings back some of that magic from that scene. I played LOL after moving on from Blizzard games (Wow was never my thing), but it wasn't the same. Also, very toxic. Not a great game for casual players.
