If you are serious about training, Training Peaks is probably a great alternative. Strava is the Facebook of activity apps so not really great if you’re committed. There is a free plan for TP, but I’m not sure what the limitations are… I pay for it and can track the history of the key metric that matter to me such Power, Heart Rate, Training Zones, Freshness, Power bands etc. There are a LOT of analytical graphs to provide insights into your progress. The key is the more data you collect, the more value there is. i.e. Sleep tracking, weight, HRV, cadence etc.
OK. Never played SC so honest question here; What is wrong if the game is technically not complete? I mean the way I thought is that this means that it keeps evolving and expanding so new content and features become available as the game development progresses. What am I missing? Is this a similar situation to the Eve Online BitterVets?
