Verdict

The call

The clearest difference is price: Iron Prototype at Free against LEGO® Marvel Super Heroes's $4.99. Iron Prototype also leads on rating (3.9 vs 3.4) and update cadence (monthly vs every 11 months). LEGO® Marvel Super Heroes's advantage is ads (none vs shown) and ratings volume (3.6K vs 21). On in-app purchases, monetization model and device support there is nothing between them.
