Pre-shipyard was easily the game at its peak. You had the trader ships that got you into it, allowed you to earn credits and experience, which was all you needed, credits and universal rank experience. Then you worked on your own customizable ship once you unlocked it. All that was needed really was to add more, actual ship concepts into this, but then someone along the way decided "lol why do that when world of tanks" and then we got tiers.
It's "sensible" in business terms, but it's shallow in terms of actual game/content/entertainment. It also creates the tiers showing up into areas they have no business being in. Game's playable, it's why I'm here. but I won't pretend for one moment that this world of tanks BS in any way made the game better. It made it "longer" but definitely not better for anyone but greybox tryina' get a quick buck outta me. Which again, is fine I guess. I've chugged about 350$ into it just to avoid the plague that is tier 3. Though I can't help but think I would have rather that money of gone to actual content generation and not simply perpetuating knockoffs of the same dozen or so existing ships we have. Just my two cents, or more, arguably. lol.
