Critial Points: What Matters Most When Picking Co-Op Games
✅ Invite friends fast (Discord integration helps!)
✅ Zero paywalls unless cosmetic
✅ No annoying spam ads interrupting gameplay
If League crashes too much during key match starts… it's a signal. Step back from client-based stuff. Try different games entirely —games where pressing "start now" means it works 🙏 That browser magic still hits hard, and honestly… there's no shame in simple joys when playing with your gang at home or online!
