The GI Joe clash-like (GI Joe: War on Cobra) actually has some nice ideas for base design. Ultimately the game isn’t great because troop upgrades come from random chests and paying players have vastly better troops. But that’s not the base designers’ fault.
The basic set-up: you start at the bottom of the enemy base, going up a long semi-wide area, with the lightly-armed HQ at the top. A strip of usable ocean runs up the right side, giving the option to try your few naval forces. The 2 resources, gems and oil, are at fixed spots along both edges. Defenders have a few short indestructible wall sections, but they can be fired over. Otherwise they place the usual array of guns and defending leaders.
Placing your attack troops costs energy, which you get more of for destroying buildings. You’re allowed only 1 of each squad, but can place it again when it’s destroyed (if you still have the energy). It’s easy enough to completely destroy a few defenses with spells, but that’s expected — they have lots of defenses. It’s the Boom Beach style: part of your plan is “I could zap those 2, or those, or a bunch of those for extra energy… .”
Making it so you can’t move around your gem and oil mines works well, It encourages more spread-out defenses to avoid giving the attacker free points for destroying them. Troops can be controlled pretty well. It’s clever, you drag the troop’s icon over to the new target. You don’t need to use this often since troops are fairly smart, and prefer killing defenses. This makes the game somewhat un-clashy.
I’m not sure this next thing really helps. All weapons need to be within a few spaces of a tough energy generator building. You get lots of those, but not one for each gun. It mostly prevents you from setting one lonely gun to guard your ocean-based oil wells.
This game uses the terrible feature where troops are always ready but need to be repaired when damaged, which is very expensive in this game. It really penalizes losing and encourages you to attack only weak bases. Luckily, the game does a bad job selecting opponents and you can often find suitable targets. In return, your base will only be steam-rollered by players far out-ranking you. Both of those get old, fast.
As a bonus, if you’re a big GI Joe fan the characters here vaguely resemble the real ones.
